Seattle Seahawks head coach Pete Carroll has insisted that there have been "no complications" with wide receiver Percy Harvin's comeback from a hip injury.

Harvin was due to return to action after being activated from the physically unable to perform list against the St Louis Rams but missed the game and underwent an MRI to ensure there were no problems.

"Yeah the doctors have looked at him. We did another MRI to make sure we were seeing everything right," Carroll told the club's official website. "There were no complications and all of that so we're just bringing him back.

"We've been quiet on him. He's not playing Sunday, we've been quiet with him, he's a little sore from last week so we're just making sure that he'll be ready to go and we won't waste our opportunity with him on the practice field."

The Seahawks are 7-1 in their season going into week nine.
