SAN DIEGO (AP) - The San Diego Chargers say they'll place guard Scott Mruczkowski on season-ending injured reserve Thursday due to a concussion.
He was hurt in Sunday's loss to the Chicago Bears that dropped the Bolts to 4-6 and into a tie for last place in the AFC West. Mruczkowski was filling in for Kris Dielman, who suffered a concussion Oct. 23 at the New York Jets and then had a seizure on the flight home.
The Chargers, who've lost five straight games, host Tim Tebow and the Denver Broncos on Sunday.
