Seattle Seahawks wide receiver Doug Baldwin left the season opener against the Denver Broncos in the first quarter with a knee injury. He briefly returned to the field but was ultimately ruled out of the game.

Coach Pete Carroll announced during his postgame press conference Baldwin had suffered an MCL sprain.

“He’s got a little MCL sprain in his other knee,” Carroll told reporters. “And so we’ve just got to see what that means. He went back in the game and played some but we just eventually talked him out of playing because he wanted to keep going.

“Just make sure we take care of him.”

Baldwin sat out the entire preseason with an injury to his other knee, costing him all of training camp, save for the first two practices. Carroll had declared Baldwin ‘really ready to go’ just last week.

With the new injury on Sunday, it may be a while before Baldwin takes the field on gamedays. Carroll should have an update during his Monday morning radio interview following further testing.
