NASHVILLE, Tenn. -- On Tuesday when the Titans trim their roster to 53, they can also put two players on injured reserve, designating them for return.

Those two would count against the eight players who can be put on IR during the season and be brought back to play after missing at least four games.

While the Titans have a lot of injured players right now, none appear to be four-week injuries. Perhaps TK McLendon with turf toe.

Brian Callahan has played down the severity of Kyle Philips' and Arden Key's hamstring issues and indicated that Kearis Jackson's knee bruise isn't serious. Cedric Gray (shoulder) worked on a side field this week. Mason Kinsey was in uniform working despite a broken pinky.

Looking further into IR:

If a player isn't designated for return, the team can't simply stash a player with a short-term injury on season-ending injured reserve.

When a player is placed on the list, the team submits documentation of his injury that details his injury and projected recovery time, classifying it as major or minor.

Major means the player is out for the season. Minor means the player has a timetable for recovery before the season ends and the team either needs to reach an injury settlement -- paying him for the agreed-upon duration of the rehabilitation -- or keep him on the injured reserve list until he completes his rehabs and passes a physical, when he then needs to be released. He can sign three weeks later.
