The Patriots released S Ross Ventrone from the 53-man roster on Thursday. Ventrone has gone back and forth between the Patriots' roster and practice squad this season. He has played in four games.
Ventrone spent most of his rookie season in 2010 with the Patriots' practice squad. He has one special-teams tackle on the season.
With the extra roster spot, the Patriots may activate DL Ron Brace from the physically-unable-to-perform list. This move also may indicate S Josh Barrett is healthy enough to play.
