Two members of the Seattle Seahawks defensive line had operations yesterday.
Defensive end Chris Clemons tweeted that he had undergone surgery to repair his anterior cruciate ligament and meniscus, having torn both during the side's 24-14 win over the Washington Redskins earlier this month.
Safety Kam Chancellor also required surgery for an undisclosed lower leg complaint.
He later posted a picture of himself in a walking boot on Instagram after the operation.
The Seahawks have begun their off-season, having been knocked out of the playoffs by the Atlanta Falcons last weekend.
