Seattle Seahawks wide receiver DK Metcalf is listed as doubtful to play against the visiting Buffalo Bills on Sunday. Metcalf sustained a Grade 1 strain of the medial collateral ligament in his knee last Sunday in the Seahawks' 34-14 victory over the Atlanta Falcons. Seattle head coach Mike Macdonald told reporters on Friday that there's a chance Metcalf can play against Buffalo despite failing to participate in practice all week. "It's doubtful right now for the game," Macdonald said. "It's not out of the question, 100 percent yet so we will take it to Sunday, and we'll go from there.
