The New York Giants announced a flurry of roster moves Thursday morning. LInebacker Clint Sintim (waived/failed physical) and defensive end Justin Trattou (waived/injured) were removed from the roster. Laron Scott, a cornerback/kick returner, and Bobby Skinner, a defensive tackle, were added to the roster.

Sintim, the team's 2009 second-round pick, did not play last season due to a knee injury. He had been on the Physically Unable to Perform (PUP) list. He played 24 games in his Giants career, making 11 solo tackles and getting one quarterback sack. Sintim tore his right ACL on Dec. 13, 2010 and re-tore it, as well as the patella tendon, in the preseason finale at New England on Sept. 1, 2011.

Trattou suffered heel and ankle injuries early in camp and has been unable to practice. He appeared in six games for the Giants last season, and was expected to compete for a role as a reserve defensive end this season.

Scott, as previously mentioned, averaged 30.6 yards per kickoff return last season for Georgia Souther. The 5-foot-9, 184-pound undrafted free agent, was waived by the New Orleans Saints on Aug. 6. He had a 67-yard kickoff return in his only preseason appearance with New Orleans.

Skinner is a 6-foot-3, 298-pound defensive tackle from Montclair State, a Division III school which is just a few minutes away from MetLife Stadium. In 10 games last season he was credited with 28 tackles (20 solo), 7 tackles for losses and 6.5 sacks.

The Giants might not be done tweaking their roster. Reports have indicated that former Denver Broncos defensive tackle Marcus Thomas is working out for the team today.
