INDIANAPOLIS – The formality of Boom Herron signing his exclusive rights tender ended on Wednesday afternoon.
Herron will be back for another season with the Colts, after he was one of the most indispensable players to their postseason run last year.
When Ahmad Bradshaw went on injured reserve in mid-November, Herron grew into the Colts lead back.
He finished the 2014 regular season with 83 rushes for 384 yards (4.6 yards per carry). In the postseason, Herron was the Colts workhorse in the backfield and recorded 128 receiving yards on 20 catches.
The burst Herron brought to the Colts backfield was on full display during a 49-yard touchdown run against Washington, the team's longest run of the season.
"He's quick, he's fast to hit the hole and once he gets outside, he's got some long speed," Chuck Pagano said of Herron after the 49-yard touchdown run.
"It's always nice to be able to get outside and get those guys loose in the secondary and have a guy that can take it the distance."
Herron's role in 2015 might look a little different with the Colts offseason program starting on April 20.
Veteran Frank Gore is expected to be the starter but Herron is deserving of reps. The Colts have always relied on multiple backs and Herron will certainly be in that mix.
Vick Ballard (coming off back-to-back season-ending injuries), Zurlon Tipton and Jeff Demps are the other ball carriers currently on the roster.
This year's draft class at the running back position is one of the deepest and the Colts would appear to be in the market for another runner with the uncertainty of Ballard's health entering 2015.
Jerrell Freeman is now the lone exclusive rights free agent remaining to sign his tender. Freeman is expected to sign it and has a few weeks before the deadline.
