Muasau (hamstring) is active for Sunday's game against the Buccaneers, Dan Salomone of the Giants' official site reports.
Muasau was sidelined for Week 10 against the Panthers due to a hamstring injury, but he will return for Week 12 after practicing in a limited capacity all week. The rookie sixth-round pick mostly has served on special teams this season, logging 11 tackles (seven solo) and one interception through eight regular-season games.
