Philips (hamstring) was placed on injured reserve Tuesday, Jim Wyatt of the Titans' official site reports.
Philips showed up on Tennessee's injury report last Friday with an ankle issue, which left him inactive in Week 7 against the Colts. The injury will now keep him sidelined for at least the next four games. With Treylon Burks (toe) also on IR, the Titans' receiving corps will consist of Robert Woods, Nick Westbrook-Ikhine, Cody Hollister and newly signed Chris Conley.
