This one involving their most expensive offseason acquisition, Percy Harvin.
The Seahawks' new offensive toy has suffered an unknown hip injury that landed him on the physically unable to perform list when training camp opened Thursday.
The injury is in the area of Harvin's labrum, which has immediately drawn concern that it could be a problem that would cause Harvin to miss significant time before ever seeing the field with his new team.
"Percy has a hip issue that he's dealing with that came up over the summer. We're trying to figure it out. We're going to do everything we can to help him out, to make the right decision and take care of him in every way," Seattle coach Pete Carroll said. "He was working out just a week or so ago going full speed, but it was bothering him enough we took some looks at it and we're going to try and figure out what the right procedures to take care of him and get him back out on the field."
Carroll did not rule out surgery as the solution, but felt the team has time to get Harvin ready.
"We're going to go ahead and do it step by step right now," Carroll said. "I know he was working full speed just a few days ago but we need to take care of him."
The Seahawks made an aggressive move to bolster an already potent offense when they traded three draft picks, including their 2013 first-round selection, to Minnesota in exchange for Harvin. Then Seattle locked up Harvin long-term, signing him to a six-year extension.
Adding Harvin to an offense already featuring Russell Wilson, Marshawn Lynch and Sidney Rice immediately raised the Seahawks' already lofty status as contenders in the NFC.
Now the plans for seeing Harvin on the field could be delayed, significantly.
If surgery is needed, the Seahawks could be looking at an extended period without their splashy offseason acquisition. Sidney Rice had surgery to repair the labrum in his hip before the start of the 2010 season and he missed more than half the season.
"Right now we need to get more information. We don't know enough right now," Carroll said.
Along with Harvin, Seattle also started camp with defensive end Chris Clemons (knee) and tight end Zach Miller (foot) on the PUP list.
