The Patriots announced that they have claimed defensive lineman Bruce Gaston off waivers from the Arizona Cardinals.
The Patriots also released linebacker Chris White.
In announcing these roster moves, the Patriots formally announced their trade of Ryan Mallett to the Houston Texans and the team's waiver claim of defensive tackle Kelcy Quarles.
Gaston, 22, was cut by the Cardinals on Saturday as teams trimmed their rosters to 53 players. The undrafted rookie played his college ball at Purdue, where he tallied 131 tackles, seven sacks, and two forced fumbles in his career.
