Hagler first Colts' starter lost for season

Posted by ESPN.com’s Paul Kuharsky

Tyjuan Hagler wasn’t supposed to be in the Colts’ defensive lineup this year.

But when he outplayed Philip Wheeler in the preseason, he regained a starting role.

Now he’s finished for the year with a ruptured biceps, and Indianapolis gets yet another test of its depth. Wheeler, or possibly undrafted rookie free agent Ramon Humber, will take over on the strong side.

While the Colts have had a good share of injuries to plenty of key players -- Anthony Gonzalez, Bob Sanders, Kelvin Hayden, Marlin Jackson and Adam Vinatieri among them -- Hagler is just the fourth player and first starter to land on IR.

He is tied for third on the team with 36 tackles.

One of the reasons Wheeler was in line to take over the spot in the offseason was because he’s a bit bigger with about two extra inches and five extra pounds, according to the current official heights and weights. (Humber is smaller than Hagler.)

But the team’s desire to gain some size didn’t trump production.

Now it’s left hoping it can get both.
