RENTON, Wash. -- Seattle Seahawks coach Pete Carroll said that the team won't know Percy Harvin's playing status until later this week, after the banged-up receiver goes through the NFL's mandatory concussion protocol.
Harvin suffered a concussion late in the first half of Saturday's 23-15 NFC divisional playoff victory over the New Orleans Saints.
"We [are] fortunate that we got the extra day," Carroll said Monday on his 710 ESPN Seattle radio show. "That really helps in these kinds of situations.
"We'll just see how he does. We won't know until Wednesday or Thursday until after all the tests are run."
The Seahawks will host the San Francisco 49ers in Sunday's NFC Championship Game. Harvin did not play in either of the two regular-season games between the division rivals.
Harvin tried to make a leaping catch in the end zone late in the first half Saturday before falling backward and hitting his head on the turf.
Harvin, who had major hip surgery on Aug. 1 to repair a torn labrum, was playing in only his second game of the season and his first since his debut Nov. 17 against Minnesota.
He also came out in the first quarter Saturday after he took a big hit from New Orleans safety Rafael Bush. Harvin caught three passes for 21 yards in the first half and had one carry on an end-around where he gained 9 yards.
