SEATTLE — Percy Harvin's return didn't last long.
The Seahawks receiver left Saturday's 23-15 division-round win over the Saints with a concussion. Seattle coach Pete Carroll said Harvin's status for the NFC title game likely won't be known until late this week.
The former Florida Gator, whose only other game since offseason hip surgery was Nov. 17, was hurt while trying to pull in a pass late in the second quarter. He took a hard hit in the end zone, and his helmet appeared to make hard contact with the turf.
Harvin was taken to the locker room, one of two trips he made to be evaluated for a concussion. On Seattle's first possession, he was dropped by Saints safety Rafael Bush, who was penalized for hitting a defenseless receiver. Harvin didn't miss any snaps.
Pregame skirmish: Saints tight end Jimmy Graham got into an incident with several Seahawks during pregame warmups. Graham exchanged words with and ripped a knit cap off the head of linebacker Bruce Irvin. Other Seahawks joined the exchange, and Graham had to be restrained by a member of the Saints staff. After the game, the Seahawks downplayed the incident, saying it resulted from both teams being amped up.
Colts: Former Patriots receiver Deion Branch, signed last week, was inactive.
Patriots: Conflicting reports surrounded linebacker Brandon Spikes going on injured reserve last week. The former Gator, who has dealt with a sore knee for most of the season, angered coach Bill Belichick by being late to a walkthrough Jan. 3 because of snow, according to espn.com. But the Boston Herald reported that was not true, saying the pain simply had become too much to overcome.
