T.Y. Hilton recently underwent surgery, according to GM Chris Ballard. As a result, the Colts will be forced to move the wide receiver to injured reserve to start the year (Twitter link via Stephen Holder of the Indy Star). 
Hilton suffered an undisclosed upper back/neck injury in practice recently. It’s a frustrating setback with lousy timing, but Ballard says that Hilton is already starting to feel better.
Hilton, of course, is a team icon who currently ranks third on the Colts’ all-time receiving yards list. He has spent his entire career in Indianapolis since being selected in the third round of the 2012 draft. The two sides avoided divorce this year, even after allowing Hilton to reach the open market.
While Hilton is out, the Colts will turn to Michael Pittman, Parris Campbell, and Zach Pascal for offensive firepower. They might be able to get by for now, but they’ll surely miss Hilton’s deep threat potential and experience in the coming weeks.
