The departure of Meriweather, which a league source told NFL Network's Albert Breer came after attempts to trade the safety failed, might be the biggest surprise. Meriweather played deep into the fourth quarter of Thursday night's 18-17 preseason loss to the New York Giants, fueling speculation that he could be on the outs in New England.
Among the other players waived by New England on Saturday were defensive linemen Landon Cohen, Aaron Lavarias, Alex Silvestro and Eric Moore; linebackers Niko Koutouvides and Markell Carter; tight ends Lee Smith and Will Yeatman; wide receiver Tiquan Underwood; offensive lineman Thomas Austin; running back Eric Kettani and defensive back Ross Ventrone.
Running back Kevin Faulk and defensive linemen Ron Brace and Brandon Deaderick were placed on the reserve-physically unable to perform list. Fifth-round pick Marcus Cannon, an offensive lineman, was placed on the reserve non-football injury list.
