The Titans signed defensive end Pannel Egboh and placed Keyunta Dawson on injured reserve with a hamstring injury.
Dawson left Sunday's overtime victory over Detroit with the injury.
Egboh was on the Titans' practice squad last season and on the 53-man roster to start the 2012 season but was inactive. He was released after the loss to New England.
At 6-6, 288, Egboh can play almost any defensive line position.
