The Patriots signed DL Terrell McClain on Wednesday and released DL Marcus Forston.
McClain was a 2011 third-round pick of the Panthers. As a rookie, he started 12 games and had 19 tackles, one sack and one fumble recovery. Carolina released McClain prior to the 2012 season.
Forston, an undrafted rookie out of Miami, was inactive for the first two games of this season. He appeared in Sunday night’s game against Baltimore.
