ALAMEDA, Calif. (AP) — A person familiar with the situation tells The Associated Press that Oakland plans to put defensive end Justin Tuck on season-ending injured reserve because of a torn pectoral muscle.

Tuck was hurt while trying to tackle Denver running back C.J. Anderson in Sunday's loss to the Broncos. He is expected to undergo surgery soon and will be placed on injured reserve some time before Oakland's game at San Diego on Oct. 25.
