RENTON — Reinforcements are coming, just when the Seahawks catch another injury.
Seattle officially activated wide receiver Percy Harvin on Monday from the physically unable to perform list, giving him a chance to play his first game for the Seahawks on Sunday.
Harvin had hip surgery Aug. 1 and has been out since. The Seahawks traded their first-round draft choice (No. 25 overall) and one of their three seventh-round picks (No. 214 overall) in 2013 as well as a 2014 third-round choice to the Minnesota Vikings for him in the off-season.
If he practices all week, Harvin could debut Sunday at CenturyLink Field against his former team.
“He’ll be going after it this week and see how far we can take it,” coach Pete Carroll said. “If everything works out well, he’ll practice Wednesday and we’ll start the process.”
Harvin being activated from the PUP list doesn’t guarantee he will play Sunday. He could still be placed on the inactive list for game day. If the Seahawks did not activate him to the 53-man roster by Monday, Harvin would have had to spend the rest of the season on the PUP list.
The Seahawks are also trying to figure out the seriousness of the groin injury cornerback Brandon Browner suffered Sunday against Atlanta. Browner left the game in the first half and did not return.
“It looks pretty serious,” Carroll said. “We’ll know more later in the week here. He’s got a substantial groin issue.”
Carroll was unsure Monday if Browner was out for the year.
If Browner is out at all, cornerback Walter Thurmond will slide into his spot. It would also mean more playing time for Byron Maxwell and Jeremy Lane, especially when Seattle shifts into nickel packages.
Left tackle Russell Okung, right tackle Breno Giacomini and center Max Unger are expected to join Harvin at practice Wednesday.
Okung has been out since Week 2 because of a toe injury. He was placed on short-term injury reserve with a return designation. By rule, that meant he had to miss eight games and the first time he could return would be Sunday. He sounds on track to do that.
Giacomini had knee surgery Sept. 30 and began to practice last week. He may be ready Sunday.
Unger suffered concussion symptoms that forced him out of the Week 9 game against Tampa Bay. He did not practice last week and was not active against the Falcons. Carroll said Unger will be back this week.
That’s a mammoth push for an offensive line that has been without its starting tackles for a majority of the season. Both Okung and Unger were named to the Pro Bowl after last season. In their absence, the Seahawks were forced to shift guard Paul McQuistan out to left tackle and have rookie Michael Bowie at right tackle.
Rookie Alvin Bailey also played left tackle on third down and, later, right guard when J.R. Sweezy came off the field because of dehydration against Atlanta.
With the starters back, the Seahawks go from thin and inexperienced to deep with options.
They are also hoping defensive captain and end Red Bryant can return. He missed last week with concussion symptoms.
