Allen would not discuss details of the meeting but said McClain would remain on the roster in a backup role after starting nine games this year before his suspension.
"I laid out exactly what the expectations are for him moving forward," Allen said. "Really that's about it. We're moving on from there. Rolando's part of this team and we're going to move on."
McClain had not been at the team's facilities since Nov. 28 when he was kicked out of practice following an argument with Allen. McClain was told not to return to practice and was suspended two days later.
That McClain is back with the Raiders is somewhat surprising considering he posted several comments on Facebook criticizing the team after he was sent home from practice. Those comments were later removed.
"Things get said in the heat of the moment," Allen said. "We've gotta move on."
McClain practiced with Oakland's second-team defense Wednesday while Omar Gaither, who started at middle linebacker in place of McClain the past two weeks, continued to work with the starters.
In 41 career games with Oakland, McClain has 6 1/2 sacks, one interception, one forced fumble, no fumble recoveries.
