He recovered a fumble, broke up two passes and returned an interception 70 yards for a touchdown. Washington was suspended for the team's first two games of the 2008 season for a violation of team rules. "I'll be honest and admit I made a mistake," he said. "That's the only way you can handle it. The best thing to do is just be honest."
When he returned, he spent most of the season as a reserve, starting two games at boundary cornerback. He managed just 22 tackles (18 solos) with a fumble recovery and a 34-yard interception return. Washington joined receiver Brian Hartline and running back Beanie Wells as three Ohio State underclassmen to declare for the 2009 NFL draft.
