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.
