SEATTLE - Pete Carroll provided a few injury updates after his team's 23-17 Week 16 loss to the St. Louis Rams at Seattle's CenturyLink Field.

On tight end Luke Willson, who suffered a concussion and did not return to the game, the Seahawks head coach said, "I don't know how serious it is. He couldn't come back."

Wide receiver Tyler Lockett was also evaluated for a concussion after coming down hard after going up for a deep ball from quarterback Russell Wilson that Rams cornerback Trumaine Johnscon intercepted. Lockett later returned.

"Lockett got banged up," Carroll said. "But he came back and played OK."

Lockett finished with three catches for 33 yards.

"I just fell the wrong way, so they had me go in there and run [concussion protocol] tests, and I ended up passing the test," Lockett said. "So I was good."

Asked about any other injuries to come from Sunday's loss to the Rams, Carroll said defensive end Cassius Marsh had a sore ankle, but continued to play, and tight end Cooper Helfet "got hit in the thigh," but stayed in the game.

"We'll see how that goes in the next couple days," Carroll said. "I can't tell you anything more about that."

When asked about the potential return of running back Marshawn Lynch (abdomen), who has missed the past six games as he continues to recover from surgery, Carroll said, "We'll see in the next couple days what that means."

Wilson, meanwhile, who was sacked four times and took 13 hits, came out of Sunday's contest "good to go."

"It's football, so you just keep battling," said Wilson. "I was fine. I'm good to go."

And in his postgame meeting with the media, wide receiver Doug Baldwin said the hamstring injury that had him listed as questionable for Sunday's game is "fine." Against St. Louis, Baldwin set a franchise-record for receiving touchdowns in a single season (14) and topped 1,000 yards receiving on the year.
