The Colts lost two players to season-ending knee injuries -- linebacker A.J. Edds and offensive lineman Ben Ijalana -- in their opening training camp practice.
"Obviously they're done for the year which is really sad," coach Chuck Pagano said. "You hate to lose anybody in camp or at any time during the season especially Ben. The guy came back, had a significant knee injury (last season), same knee, two hip surgeries, busted his rear to get healthy and get back and then unfortunately something like this happens. A.J., the same thing, all the hard work and time and preparation these guys have put in and then to come out here and in basically a non-contact drill and it happens."
Ijalana was a second-round pick in 2011 and tore the same ACL in the same knee after four games as a rookie. He was downgraded prior to the draft because of a history of hip injuries at Massachusetts. Ijalana was competing with free agent Joe Reitz at left guard.
Edds, a third-year pro, was behind Kavell Conner at left inside linebacker.
The Colts were likely to add to the roster, possibly by Wednesday, Pagano said.
"Grigs (GM Ryan Grigson), he doesn't sleep," Pagano said.
The Colts' players were scheduled for an off day Wednesday.
