Seahawks left tackle Michael Bowie suffered a fractured left ankle and will miss four to six weeks, according to the team.
Bowie was taken off the field with a right knee injury and left the field without a leg brace.
The team announced Monday that Bowie was listed in good condition on his personal injury report.
Bowie suffered the injury while blocking for Marshawn Lynch in a Week 10 game against the Arizona Cardinals.
The Seahawks have already lost offensive lineman John Moffitt to a knee injury, guard Dan Feeney to a sprained MCL and guard Alex Boone to a shoulder injury.
