On more than one occasion during Rams training camp, tight end Justice Cunningham has been seen limping off the practice field. Once, he even received a short cart ride to the locker room.

But without fail, when practice starts the next day, Cunningham is there, working with teammates.

“Just a bunch of little things that you have to get through, nothing real serious,’’ he said following practice Thursday. “Playing football, you’re going to have aches and pains, but you just have to fight through to make sure you’re out there the next day.’’

To be honest, the 6-foot-3, 258-pound Cunningham doesn’t have the luxury of taking time off these days. He is one six tight ends on the roster and currently in a heated battle for a roster spot.

The team figures to be set with veterans Jared Cook, who led the Rams in receiving a year ago with 51 catches for 671 yards and five touchdowns, Lance Kendricks (32 catches, 258 yards, four TDs) and Cory Harkey (13 catches, 113 yards, two TDs) to lead the way. After that, there’s Cunningham, rookie free agent Alex Bayer, who led the team in the preseason opener with five catches for 71 yards, and newcomer Brad Smelley, who was picked up after defensive lineman-turned-tight end Mason Brodine went to injured reserve with a fractured ankle.
