Harvin doesn't practice Thursday

RENTON, Wash. -- Seattle Seahawks receiver Percy Harvin did not practice again Thursday, which brings continuing doubts about the chances of him playing Sunday at San Francisco.

Seattle coach Pete Carroll said Harvin would run on his own before practice Wednesday and they would evaluate where he was in terms in practicing Thursday.

Harvin made his season debut Nov. 17 against Minnesota but did not play Monday night against New Orleans because of soreness in his surgically repaired hip.

Linebacker Bruce Irvin, who has a thigh injury, also has not practiced this week, but Carroll said Wednesday that he expected Irvin to play this weekend.

Cornerback Brandon Browner, who was a limited participant in practice Wednesday, did not practice Thursday. Browner has a strained groin, but he is also awaiting word from the league in his appeal of a possible one-year suspension for violating the NFL’s substance-abuse policy.

Backup quarterback Tarvaris Jackson missed practice because of an illness. Tight end Kellen Davis (strained neck) was limited.

Receiver Golden Tate and running back Marshawn Lynch returned to full practice participation.
