NFL.com's Ian Rapoport reported Friday that Rice has returned from Switzerland after leaving training camp this week to undergo a non-surgical procedure on his knee, according to a source who talked with the player. Rice, per the source, is expected to return early in the preseason. As Chris Wesseling pointed out, players are known to voyage to Europe for the blood-manipulation treatment known as Regenokine, but the Seahawks have given no specifics on Rice's trip. Coach Pete Carroll told reporters Tuesday he was optimistic Rice wouldn't miss any game action, suggesting the pass-catcher would be ready for Seattle's preseason opener on Aug. 8 against the San Diego Chargers.
