Young went down while scrambling, immediately grabbed his left leg and had to be helped off the field in the fourth quarter. He missed a victory against Philadelphia last week with a sprained left knee and ankle.
Young was 10-of-21 for 253 yards and 2 touchdowns (123.7 passer rating) before leaving the game.
Young was in a walking boot as he left the locker room after the game.
"It's very tough," he said. "I definitely want to be out there with my teammates. It's very frustrating. I hate putting them in that situation, but we have an outstanding backup quarterback."
Young was replaced by Kerry Collins.
The Titans are off next Sunday.
"The bye is good, to get back to rest a little bit and get more treatment and get off of it and let it rest," Young said.
The Titans also lost Kenny Britt to a right hamstring injury in the first quarter. The second-year pro had a career day against the Eagles last week with seven catches for 225 yards.
