Percy Harvin, who suffered a concussion in Saturday’s win over the New Orleans Saints, is still undergoing tests for his head injury. His status for the NFC Championship game will not be known until Wednesday or Thursday, according to head coach Pete Carroll.

Carroll spoke on 710 ESPN earlier Monday morning and said he doesn’t know much detail about the injury, via Nick Eaton at the Seattle Post-Intelligencer:

"“Nothing yet,” Carroll said Monday on 710 ESPN Seattle radio’s “Brock and Danny Show.” “We’re fortunate to get an extra day (of rest), and it really helps in these kind of situations. And we’ll just see how he does. I won’t know, we won’t know, until Wednesday or Thursday, until we get all the tests run and the protocol taken care of and all of that.”"

Harvin received his first blow to the head on the Seahawks third offensive play of Saturday’s game, a helmet-to-helmet shot from Saints safety Rafael Bush. Harvin was taken to the locker room for evaluations but returned to the field soon after the hit.

Near the end of the first half, Harvin was hit again and landed on his head in the back of the end zone. He left to the locker room after the play and did not return. The official diagnosis was a concussion.

Harvin was playing for the first time since Nov. 17. He has been dealing with a hip injury all season, but was finally cleared to play on Saturday after having multiple issues with the hip.

The Seahawks will host the San Francisco 49ers on Sunday in the NFC Championship game.

This is the third time in franchise history the Seahawks have been in the conference championship. It is the 49ers third-consecutive year in the conference championship.
