The veteran was in his second season with the Titans and finishes 2014 with 27 tackles and one sack in five games. Last season, Pollard had 99 tackles and three interceptions.
Locker, who left Sunday's game in the second quarter with the injury, appears to have no structural damage in his thumb. He was replaced by backup Charlie Whitehurst, and the Titans squandered a 25-point lead and fell to Cleveland, 29-28.
Tennessee is 1-4 and in third place in the AFC South. The Titans play in Jacksonville next Sunday.
