Who will be the Titans' fourth receiver?

NASHVILLE, Tenn. -- Derek Hagan wasn’t in the league last year.

Now he’s part of a group set to battle for the Tennessee Titans' fourth wide receiver job.

The Titans' first three are clear: Kendall Wright, Justin Hunter and Nate Washington.

After that, it’s going to be a scramble.

Michael Preston is an impressive worker and an impressive guy, and he made some plays in limited chances last season. Marc Mariani has missed the past two seasons hurt, but the new staff seems to like him on offense. Brian Robiskie and Hagan rank as veteran journeyman, each on his fifth team. (Hagan says he has stayed ready.)

My prediction: I think Preston and Mariani will be the prime contenders, but I think the better of the two winds up the fifth guy and the other is the sixth, though the team could decide to keep only five.

So who will be No. 4?

An outsider who is cut when rosters around the league are trimmed to 53 on August 31.
