Sidney Rice has returned to Seattle after the Seahawks wide receiver sought treatment for a sore knee in Switzerland.

Rice was mostly a spectator on Friday as the Seahawks held a scrimmage while preparing for their preseason opener next Thursday at San Diego. Rice caught a few passes on the side and coach Pete Carroll said he is expected to return to practice on Sunday.

Rice flew about 10,000 miles round trip to Switzerland to have a plasma injection into his knee to help with patella tendinitis. Rice spent two nights in Europe and said the procedure took only about 20 minutes. He arrived back in Seattle on Thursday.

Rice hopes the procedure reduces the discomfort the tendinitis has caused.
