Miss. Code § 23-15-643
If an affidavit is required, the appropriate election officials shall examine the affidavit of each absentee ballot envelope. If the officials are satisfied that the affidavit is sufficient and that the absentee voter is otherwise qualified to vote, an official shall announce the name of the voter and shall give any person present an opportunity to challenge in like manner and for the same cause as the voter could have been challenged had he presented himself personally in such precinct to vote. The ineligibility of the voter to vote by absentee ballot shall be a ground for a challenge. Also, the officials shall consider any absentee voter challenged when a person has previously filed a written challenge of such voter's right to vote. The election officials shall handle any such challenge in the same manner as other challenged ballots are handled.
