Seattle Seahawks defensive coordinator Ray Rhodes, who had a mild stroke two months ago, was hospitalized Friday after another "episode" and will miss Sunday's game at Arizona. "It wasn't as severe as the first one," coach Mike Holmgren said, declining to say if Rhodes had another stroke. "I'll let the medical people define that," he said. The Seahawks wouldn't say where Rhodes was hospitalized. Rhodes missed the Seahawks' opener at Jacksonville Sept. 11 after being hospitalized for two days after complaining of dizziness. Doctors diagnosed his medical problem as a mild stroke. Linebackers coach John Marshall has been serving as Seattle's defensive coordinator this season although Rhodes has been sitting next to him in the press boxes at games. Rhodes will not be in Arizona, Holmgren said. Holmgren said Rhodes "started feeling really tired last night" and called his doctor after arriving at work at the Seahawks' headquarters Friday morning. Rhodes then was advised to go to the hospital, Holmgren said.
