He went in for x-rays (which were negative) and said he would be back at practice today (Thursday).
"It was something from the game the other day," Collins said. "Toward the end of practice I just kind of tweaked it a little bit. It was a little bit of a spasm. It's not a big deal at all."
Collins told the team trainers of his back problem on Sunday after the loss to the Texans. However, it did not bother him again until practice yesterday.
Collins is not listed on the injury report and should start his 50th consecutive regular-season start for the Giants.
