Red Sox general manager Theo Epstein announced Wednesday night that Youkilis was placed on the 60-day disabled list as the corresponding move to the team's activation of right-handed pitcher Clay Buchholz from the 60-day DL.
Youkilis is suffering from a sports hernia, has bursitis in his hip and will need offseason surgery, but he was hoping to play through the pain in order to help the Sox.
"I don't know if it's been ruled out, but I think the writing's on the wall. I don't think you're going to see him play again," Red Sox manager Terry Francona had said before the move was announced. "I wish he would, he's tried so hard and has been open to doing anything, but I just don't know if that's going to happen. I don't think it's 100 percent but it's getting there."
Youkilis sat on the couch in the visitor's clubhouse at Camden Yards and said he's in a holding pattern.
"I've got nothing new. Wish I had something, but I've got nothing right now," he said. "I'm in a holding pattern and seeing what's going on with this team and that's about it."
He also didn't know whether or not he'd be available for the postseason if the Red Sox get there.
"I couldn't tell you yes or no on that one," he said. "We're just in a holding pattern. It's up to them, too."
The waiting game is finally over, as the Red Sox have decided to shut him down for the season.
