Muasau (ankle) is listed as questionable for Sunday's game against the Commanders, Matt Citak of the Giants' official site reports.
Muasau had his 21-day practice window opened Tuesday and was able to log full participation in all three sessions this week. The return of the inside linebacker could be a needle-mover for this Giants defense, especially with the potential absence of Demetrius Flannigan-Fowles (illness/neck/knee).
