Until this past week against the Ravens, the Patriots have been mostly fortunate on the injury front, unlike most teams across the league. Although they've lost some key starters, they've been placed on injured reserve and are expected to return for the playoffs, which is a much better scenario for a team in their position.
Because of that, a player like DT Milton Williams can return as soon as this week against the Jets, and according to Mike Vrabel, there's a good possibility that will happen.
The defensive tackle suffered an injury last month that landed him on IR, and he has now missed four games, meaning his return window can finally be opened this week.
