Vaccarol (ankle) is listed as inactive for Monday's game against the Falcons, Josh Katzenstein of The Times-Picayune reports.
Vaccaro recorded nine tackles and a forced fumble in Week 2's loss to the Giants, but also came out of the game with an ankle injury. He was unable to practice throughout the week, which ultimately led to a questionable designation for Monday's contest. Roman Harper figures to fill in for Vaccaro in his absence.
Snead is officially listed as questionable due to his toe injury but apparently won't be available Monday night, barring an unforeseen improvement. After an explosive first couple games this season, Snead's absence figures to open more opportunities for rookie Michael Thomas and Brandon Coleman as complements to Brandin Cooks against a vulnerable Falcons pass defense.
Breaux (lower leg) has been ruled out for Week 3.
Breaux suffered a broken fibula against the Raiders in Week 2 and isn't expected back until Week 8.
Vaccaro was able to take the practice field on Saturday after failing to do so on both Thursday and Friday. Should he be ruled out prior to kickoff, Roman Harper figures to slide into the starting lineup.
Snead logged a limited practice session Saturday after failing to participate on both Thursday and Friday. If he's ultimately cleared to play, a matchup against a Falcons defense that has allowed a league-worst 74 percent completion rate to opposing QBs will await.
