Wallace (quadriceps) was a full participant in practice Thursday after participating on a limited basis Wednesday, Jim Wyatt of the Titans' official site reports.
The starting free safety appears on track to play Sunday against the Texans. Wallace was claimed off waivers by the Titans on Oct. 25 and has played 85 percent or more of the defensive snaps in each of the last three games, recording 18 tackles in that span.
