The Seattle Seahawks offense finally broke out on Sunday, exploding for 37 points in a win over the 49ers. Christine Michael did a lot of the heavy lifting early, with Russell Wilson also throwing for over 200 yards in the first half.

Wilson suffered a knee injury during the third quarter, though, and left the field for a play before returning, then ceding his spot to backup Trevone Boykin for the rest of the game. Pete Carroll said he'd been planning on pulling Wilson anyway because of the Seahawks' big lead, but did confirm during a Monday radio appearance that Wilson has a sprained MCL, according to

"He's in good spirits, just like you would think," Carroll said. "He has no intention of thinking anything other than that he's playing."

For his part, Wilson said the knee injury wasn't as "severe as it looked. I have good mobility. ... You always feel better when you win."

Wilson then tweeted on Monday morning that he is grateful, which many Seahawks fans in his mentions assumed meant he got good news on his knee (an MRI was taken to confirm the injury wasn't serious).

In another boat is running back Thomas Rawls, whose fibula injury is more serious than the Seahawks initially thought, according to Carroll.

Rawls' likely absence means it will be the Christine Michael show for the next few weeks. Michael re-signed with the Seahawks late last season after Rawls broke his ankle; he had been traded to and released by the Cowboys earlier in the year.

The Seahawks spoke during the preseason of a "reawakening" for Michael, and he's looked excellent in the early going of the season.
