RENTON, Wash. -- The Seattle Seahawks defensive line took a hit as the team placed defensive tackle Jason Jones on injured reserve with a lingering knee injury.
The Seahawks made the move Thursday and promoted defensive tackle Hebron Fangupo from the practice squad to takes Jones' roster spot.
Jones signed a one-year deal with the Seahawks in March to add depth to the defensive line rotation. He's recorded three sacks playing mostly in passing situations and had a fumble recovery, but was hampered by a knee injury.
The loss of Jones, coupled with concerns about Alan Branch's availability due to an ankle injury, could leave the Seahawks thin on the defensive line for Sunday's matchup against San Francisco.
Fangupo was signed to Seattle's practice squad on Sept. 11. The Seahawks added wide receiver Bryan Walters to the practice squad.
