Chargers LB Polk suffers torn left Achilles tendon June 16, 2005SAN DIEGO (Ticker) - San Diego Chargers backup linebacker and special teams standout Carlos Polk suffered a torn left Achilles tendon during an offseason workout session on Wednesday and may miss the entire 2005 season, the team announced on Thursday. The Chargers medical staff projects a six to nine month recovery period for Polk, making mid-December the earliest time for a possible return. San Diego can place Polk on injured reserve, which would make him ineligible to play in 2005. If he gets placed on the physically-unable-to-perform list, then Polk would be required to miss at least half the season. A fourth-round pick in 2001, Polk served as a backup at both the inside and outside linebacker positions and starred on special teams in his first two seasons with the Chargers. However, last season he missed 15 games due to a shoulder injury.
