Appellant Ernest Edward Dominguez appeals from a conviction in the Western Dis-' trict of Texas for possession of heroin with intent to distribute 1 which resulted in a twelve year sentence and a fifteen year special parole term. His appeal is based on the trial court’s excusal of a seated, but unsworn juror without consultation with defense counsel, denial of a motion to suppress based on alleged insufficiencies in the affidavit supporting a search warrant and failure of the court to direct a verdict in favor of the defendant due to the government’s alleged inability to prove Dominguez was sane after the defense had presented evidence of his insanity. We find no merit in his contentions and affirm.
On December 6, 1978 an agent of the Drug Enforcement Administration (DEA) sought and obtained from a United States Magistrate a search warrant for the residence of Ernest Edward Dominguez. The application for the search warrant included an affidavit by the DEA agent which alleged that for several weeks the El Paso Police Department and the DEA had been conducting a surveillance operation at a Ranger Street residence pursuant to an anonymous telephone tip describing suspicious activity at the residence. The surveillance operation had disclosed that several known narcotics traffickers frequented the residence and that appellant Dominguez was apparently at the residence most of the time. The affidavit also recited information from two informants, at least one of whom had supplied reliable information previously, that Dominguez had sold heroin at the residence. One of the informants, according to the affidavit, had seen contraband at the residence within two weeks prior to the swearing out of the affidavit.
The warrant obtained on December 6, 1978 was executed the next day. Agents found approximately one pound of heroin in and around the master bedroom of the residence. Dominguez and three other occupants were arrested but charges were subsequently dropped against all but Dominguez.
On April 4, 1979 a jury was selected for Dominguez’ trial and April 11 was set as the actual trial date. In the interim, on April 9, the trial judge received a note from one of the jurors requesting excusal from service due to the illness and hospitalization of his 87-year old mother in New Mexico. 2 *1095 The trial judge mistakenly thought the request was from a venire member rather than from a seated juror and immediately excused the juror. He learned of his mistake the next day. Shortly before trial was to begin on April 11 he informed counsel of the inadvertent excusal and replaced the excused juror with one of the selected alternates. The defense moved for a mistrial and the court denied the motion.
Trial proceeded and, as a defense, appellant’s counsel presented four psychiatrists who testified as to appellant’s mental problems. The government offered one psychiatrist who testified in rebuttal that he had found Dominguez not to be suffering from any mental illness that would render him incapable of complying with the law. No motion for acquittal was made and the sanity issue, along with all other trial issues, went to the jury for determination. The jury decided all issues against appellant.
Rule 24(c) of the Federal Rules of Criminal Procedure provides that “alternate jurors in the order in which they are called shall replace jurors who, prior to the time the jury retires to consider its verdict, become or are found to be unable or disqualified to perform their duties.” It is settled law in this and other circuits that it is within the trial judge’s sound discretion to remove a juror whenever the judge becomes convinced that the juror’s abilities to perform his duties become impaired.
United States v. Spiegel,
There is no question that alternates may replace seated jurors when they become unable to serve. That, indeed, is the very purpose of Rule 24(c). Two facts about this case may complicate this issue somewhat, however.
First, the practice of pre-selecting a jury in one week for service the following week caused the judge to be confused about the actual status of the juror. If the juror had been merely a jury venire member the excusal would not have raised any question of abuse of the judge’s discretion. The fact that the juror was a member of the seated, albeit unsworn,
3
jury, however, implicates Rule 24(c) and involves a determination by the judge that the juror was
unable
to serve. Regardless of his mistaken belief that the excused juror was only a prospective juror, the trial judge apparently determined him to be unable to serve at the time the request for excusal was made. The excusal was not for a frivolous reason and was clearly^ not an abuse of discretion.
See, e. g., United States v. Hoffa,
The second complicating factor on this issue is that the juror was inadvertently excused outside the presence of defense counsel. Appellant claims that his right to be present at crucial points in the trial as *1096 provided by Fed.R.Crim.P. 43(a), was violated by excusal of the juror without prior notification of and consultation with defense counsel. 4 It is clear from the record that it was by inadvertence and not design that defense counsel was not present when the determination of whether the juror should be excused was made. While it is clearly the better practice to have defense counsel present when such an excusal is granted, the trial judge’s misunderstanding about the status of this particular juror does not merit reversal of appellant’s conviction in this case. 5
Appellant also urges consideration of two other grounds on this appeal, neither of which necessitate reversal. One of these claims is that the affidavit supporting the search warrant was insufficient under the two-pronged
Aguilar-Spinelli
test and defendant’s motion to suppress the fruits of the search should have been granted.
See Aguilar v. Texas,
The test requires that the affidavit (1) disclose “ ‘underlying circumstances’ necessary to enable the magistrate independently to judge of the validity of the informant’s conclusion” and (2) make some showing of reliability of the informant.
Id.
at 413,
The final ground for reversal urged on appeal is based on the failure of
*1097
the trial court to direct a verdict for appellant on the issue of appellant’s insanity. Because appellant failed to make a timely motion for judgment of acquittal this question is not properly before the court unless a failure to reach it would foster a manifest miscarriage of justice.
See United States v. Jones,
Therefore, for the reasons stated above, the conviction is AFFIRMED.
Notes
. See 21 U.S.C. § 841(a)(1).
. The note read as follows:
Judge Sessions:
I am a juror for the April 11, 1979 trial in U. S. A. v. Ernest Edward Dominguez.
My 87-year old mother is very ill in Hobbs, N.M., and may be hospitalized under Doctor Badgett’s care.
In view of my mother’s ill condition I request permission to be excused from my April 11, 1979 scheduled jury service.
Thank you very much.

. At oral argument counsel for both appellant and appellee conceded that the fact that the jury was unsworn had no real significance to the resolution of this issue. Had the jury been sworn the trial judge may have been more compelled to proceed with the chosen jury with substitution of an alternate since excusal of the entire jury may have raised double jeopardy questions. The fact that this unsworn jury could have been excused and the selection process started anew without facing a double jeopardy bar does not, however, compel the judge to adopt that procedure.
. Fed.R.Crim.P. 43(a) provides as follows:
The defendant shall be present at the arraignment, at the time of the plea, at every step of the trial including the impaneling of the jury and the return of the verdict, and at the imposition of sentence, except as otherwise provided by this rule.
In a case involving an issue similar to this the Second Circuit has recognized that situations may arise where the needs of the jurors must be considered even in the absence of defense counsel.
Situations may sometimes arise when a respect for the rights of jurors will require the judge to take immediate action without consulting counsel — e. g., if a juror is taken so ill that he cannot come to court or has a family emergency requiring him to leave during the night or over a weekend.
United States v. Houlihan,
Even if this excusal outside the presence of the defendant is error, it is well settled that Rule 43 is subject to Fed.R.Crim.P. 52(a) which provides that harmless error shall be disregarded.
See United States v. Bokine,
