EAST RUTHERFORD, N.J. – With the NFL's most productive rushing attack ready to take them on tomorrow in Charlotte, the Giants today added more bulk to their defensive line.

Tackle Josh Mauro, who missed the season's first four games while serving an NFL suspension, was activated.

To create room on the roster, the Giants placed wide receiver/return specialist Stacey Coley on injured reserve with a right hamstring injury. 

Mauro returned to the Giants on Monday, and the team was given a one-week roster exemption that was set to expire at 4 p.m. on Monday. But the Giants added him to the roster for tomorrow's game against the Carolina Panthers, who are averaging an NFL-best 166.0 rushing yards a game. Carolina had a bye last week and has played just three games.

The Panthers' rushing attack features Christian McCaffrey, one of the league's most versatile and dynamic running backs, as well as dual-threat quarterback Cam Newton.

Mauro, 6-6 and 290 pounds, signed with the Giants on March 19, three days after his release by the Arizona Cardinals. He spent his first four NFL seasons in Arizona, where he played for current Giants defensive coordinator James Bettcher. Mauro joins a defensive line rotation that includes Damon Harrison, Dalvin Tomlinson, B.J. Hill, Kerry Wynn, Mario Edwards and John Jenkins.

Mauro played in 47 games with 26 starts for the Cardinals and had 92 tackles (65 solo), 2.0 sacks, two forced fumbles, and one fumble recovery. He also played in three postseason games with two starts, and had two tackles (one solo).

Coley joined the Giants on Sept. 19, one day after he was released by the Minnesota Vikings. He played in one game – the Giants' victory in Houston two weeks ago – and returned two punts for six yards and two kickoffs for 27 yards. He did not play last week against New Orleans.
