REDMOND, Wash. -- The Seattle Seahawks activated wide receiver Percy Harvin from the physically unable to perform lost on Monday, but have likely lost cornerback Brandon Browner for an extended period - if not the season.
Harvin, who has been recovering from August hip surgery and has practiced the past three weeks, is expected to make his season debut against his former team, the Minnesota Vikings, on Sunday.
"He'll be going after it this week and see how far we can take it and if everything works out well, he'll practice Wednesday and we'll start the process," coach Pete Carroll said. "This would be considered phase three.
"He's just got to practice every day and all that he has done in the rehab work has paid off and that he can sustain through each day and it's really the next day that we always look at. He makes his day and then, 'How does he feel the next day,' and we'll just see how that goes. To us, it's not a pressured decision. We're going to try again to really consider all of the factors and make sure we're doing this right and make a real good choice as we get our information."
Seattle acquired Harvin from Minnesota on March 12 in exchange for a 2013 first-round pick, seventh-round pick and a 2014 third-round pick.
Harvin had 62 receptions for 677 yards in nine games for Minnesota last year. He is also one the league's top return men.
Browner left Sunday's game after injuring his groin while making a cut in coverage.
"It looks pretty serious," Carroll said of Browner's injury. "We'll know more later in the week here. He's got a substantial groin issue. We got to figure it out."
Asked if Browner could be sidelined for the season, Carroll said, "We'll find out. We'll know in a few days here."
Browner will be replaced in the starting lineup by Walter Thurmond, who Carroll said last week is likely the most improved player on the roster this season. Byron Maxwell and second-year player Jeremy Lane will also see increased playing time.
"Those guys have always performed really well, when called on and we feel really good about those guys," Carroll said of Thurmond and Maxwell. "They're tested, they've started games, they've played a lot, Jeremy can play as well. So we're in good shape at the position."
The Seahawks also released defensive tackle Michael Brooks, who was signed to the 53-man roster from the practice squad Saturday and had a tackle in Atlanta on Sunday.
