Percy Harvin has become one of the most electrifying players in the NFL. But he has had more than his share of injuries in four NFL seasons. He starts his first campaign in Seattle with another one.

The Seahawks announced Thursday that they have placed Harvin on the physically unable to perform list, with a hip injury.

Harvin, who arrived via trade from the Vikings and signed a big-money contract, can slide over to the active roster at any time.

Also on the PUP list for the Seahawks are defensive end Chris Clemons (knee), tight end Zach Miller (foot), defensive end Greg Scruggs (knee), cornerback Tharold Simon (foot) and running back Robert Turbin (foot). Linebacker Korey Toomer has been placed on the non-football injury list, with a knee injury.

All players count against the active roster. Coming up later today, I’ll explain why teams use the designation, if it ultimately doesn’t provide them with an extra roster spot in the interim.

UPDATE 3:05 p.m. ET: PFT has learned that Harvin could need surgery for the injury, which was detected Thursday in an MRI. The team wants to treat the injury without surgery. Harvin intends to exercise his right to a second opinion, which could result in a recommendation of surgical repair.
