Polk to IR
Today's player transactions:
The San Diego Chargers have placed linebacker Carlos Polk on the "Reserve-Injured" list with a shoulder injury.
Polk, the team's leading special teams tackler with 11, was injured while making a tackle in Sunday's game at Jacksonville. He will miss the remainder of the season.
Practice squad linebacker Jyles Tucker will take Polk's place on the active roster. Tucker is a 6-3, 258-pound rookie from Wake Forest.
The team also waived defensive tackle Tim Sandidge from the practice squad.
The two vacant spots on the eight-man practice squad will be filled by Keith Jackson, a 6-0, 315 rookie defensive tackle from Arkansas, and Terna Nande, a 6-0, 230 first-year outside linebacker from Miami of Ohio.
