Carpenter was first signed this offseason, spending training camp with the team before being released as it finalized its 53-man roster. He was named one of the team's 10 offseason award winners, and offers strong versatility to player a number of different linebacker spots. A former first-round pick of Cowboys in 2006, Carpenter has recorded 165 career tackles.
His signing could be an indication that linebacker Dont'a Hightower, who left in the second quarter of the team's Week 4 win over the Buffalo Bills with a hamstring injury, will miss practice time this week and potentially this Sunday's game with the Broncos. The team will release its first injury report of the week later Wednesday.
Silvestro was converted from defensive end to tight end this offseason, and like Carpenter, was with the team until the final roster cut downs. He was subsequently signed to the Patriots' practice squad, but his contract was later terminated. Originally an undrafted free agent out of Rutgers in 2011, Silvestro was signed to the Patriots' active roster the night before Super Bowl XLVI, although he did not play.
Comcast SportsNet first reported that the team intended to bring back Carpenter at some point this week.
