NASHVILLE — The Tennessee Titans have placed linebacker Aaron Wallace on injured reserve and signed wide receiver Zach Pascal off the practice squad.

The Titans announced the moves Wednesday.

Wallace had been dealing with a back issue since the preseason. The Titans also signed offensive lineman Brad Seaton and outside linebacker Tony Washington Jr. to the practice squad.

The 6-foot-2 Pascal was an undrafted free agent out of Old Dominion who was cut by Washington in the Redskins' final cuts. Pascal had a school-record 233 catches for 3,193 yards and 30 touchdowns in college, and he also returned kicks.

Seaton was a seventh-round draft pick by the Titans out of Villanova last spring. Washington spent the last two seasons with Houston on injured reserve and the practice squad.
