Seahawks wide receiver Sidney Rice has traveled a long way from Seattle this week for a non-surgical procedure on his knee head coach Pete Carroll said Tuesday.

“He’s actually in Switzerland” Carroll said Tuesday after jokingly asking media to guess Rice’s whereabouts.

Rice’s knee has been nagging him for a “long time” Carroll said and now is the time to try to fix it. Rice 26 was Seattle’s leading receiver in 2012 with 748 receiving yards and seven touchdowns.

With Percy Harvin’s hip injury questions are already swirling about the Seahawks’ receiving corps. Yet in his news conference Tuesday after training-camp practice at the VMAC in Renton Carroll didn’t appear worried about Rice’s injury.

“We’re really excited about what he’s doing — something he’s been working toward” Carroll said. “We’ve been working with it for a long time. The timing came up where this is when he has to take his break to go — to get his procedure — so he’s going to be gone for a couple days.

“There’s a muscle that they’re working on around the knee area” Carroll added. “I’m not going to try and tell you what (the procedure) is because this is way beyond my pay-scale. … We’re going to get him really healthy really healthy.”

It was not immediately clear what Rice’s knee procedure entails but Carroll clarified that it is not surgery.

The big question is: Will Rice miss any preseason or regular-season games?
