ALAMEDA, Calif. (AP) - Oakland Raiders left tackle Donald Penn will undergo surgery on his injured right foot.

Coach Jack Del Rio said Monday that Penn will miss the rest of the season because of the injury. Penn has appeared in all 174 regular-season games since making his debut as an undrafted free agent with Tampa Bay in 2007. Penn became a starter that season and has started 170 straight games, the longest active streak of any offensive lineman.

Penn did miss Oakland's playoff game last year against Houston with a knee injury but has otherwise been an ironman at a physically grueling position.
