McClain, the No. 8 overall pick in the 2010 NFL Draft, posted a series of messages on his Facebook account Wednesday about parting ways with the Raiders, only to delete everything. Breer and Rapoport reported that McClain's status with the team remained unchanged.
McClain has dealt with injuries and an assault arrest from 2011. He initially was sentenced to jail time, but the charges subsequently were dropped.
Those transgressions might have been ignored had McClain performed on the field, but he has struggled in pass coverage and too often has given up big plays as a run defender because he guesses wrong. McClain's playing time was reduced halfway through this season. Still, he has shown flashes of being a solid playmaker against the run at times in his NFL career.
McClain's downfall comes as a surprise because he was known for being a great leader and a heady player during his time in college. If he is released by the Raiders at some point, McClain will be subject to waivers.Follow Gregg Rosenthal on Twitter @greggrosenthal.
