Indianapolis, IN – The New England Patriots released wide man active roster.
The moves came on the eve of New England's date with the New York Giants in the Super Bowl.
Underwood played in six games for the Patriots this season and caught three passes for 30 yards.
The 23-year-old Silvestro saw his firs NFL action in a victory over Miami on Dec. 24. He was released on Dec. 29 and signed back to the practice squad two days later.
Because of the move to release Underwood, it's possible the Patriots could make wide receiver Chad Ochocinco active for the game. The other New England wide receivers are Wes Welker, Deion Branch, Julian Edelman and Matthew Slater.
