Matt Prater, who is serving the final days of his four-game suspension for violating the league's alcohol program, was notified around 11 a.m. Friday that he would be released.
"I'm a little surprised," Prater said from Florida. "The Broncos look like they're going to do some great things this year. It's too bad I won't be a part of it. I'm just going to concentrate on keeping myself in shape and hopefully I'll be kicking for someone this year."
The Broncos are sticking with Brandon McManus, who in his first three NFL games is 14-of-16 in kickoff touchbacks and three-of-three on field-goal attempts, although his longest is from 24 yards.
McManus has only kicked three field goals through three games, but he should be a quality start on an every week basis given the strength of the Denver offense.
