The Jacksonville Jaguars today placed linebacker Mike Peterson on injured reserve and signed veteran free agent cornerback Ahmad Carroll, who was released by the Green Bay Packers on Oct. 3. Peterson suffered a season-ending injury against the New York Jets when he sustained a tear of his left pectoral muscle.

Peterson, 30, started all five games this season at middle linebacker and led the team with 47 tackles (27 solo) and one interception. He had started 53 consecutive games in Jacksonville and led the Jaguars in tackles in each of the last three seasons.

In 110 career games with 107 starts, he has 1,110 tackles (633 solo), 16.5 sacks and 14 interceptions.

Carroll, 23, played in four games with one start for the Packers, recording six tackles, one sack and five passes defensed. The third-year veteran was originally selected in the first round of the 2004 NFL Draft out of Arkansas with the 25th overall pick.

The Atlanta, Ga. native has started 28 of 34 career games with 104 tackles (95 solo), three sacks, three interceptions and 26 passes defensed. He has returned 21 kickoffs for 421 yards (20.0 avg.) with a long of 57 yards and returned one fumble for a touchdown. He will wear jersey No. 25.
