Tight end Adam Nissley, an undrafted free agent from South Forsyth High and Central Florida, suffered an torn ACL last week before being released injured by the Falcons, waived-injured.

Nissley, 6-foot-6 and 267 pounds, was recovering from a torn ACL in the opposite knee that he suffered last August 9.

The Falcons signed tight end Anthony Miller to take Nissley’s spot on the roster.

Nissley got off to a bumpy start with the Falcons.

On the first day of minicamp last June, he got into a scuffle with defensive end John Abraham, who is no longer with the team. During a kickoff coverage drill, Nissley drew the ire of special teams coordinator Keith Armstrong after he jumped offsides.

Things had started to smooth out before he suffered the first knee injury.

“This has been the experience of a lifetime, to come out and play and learn football from the best guys in the NFL,” Nissley at the time.

He redshirted in 2007 and went on to play four seasons for the Knights. He was used mostly as a blocking tight end, but caught 38 passes for 465 yards and two touchdowns.

After he was not selected in the NFL draft, Nissley had calls from the New York Giants, New Orleans, Kansas City and the Falcons.

“I knew if it came down to the free agency, Atlanta would be my choice,” Nissley said.

Before the second knee injury, Nissley has been working out at the Y or the blocking tight end position.

Miller, 6-4, 260 pounds, was originally signed by the Denver Broncos as a college free agent out of California following the 2012 NFL Draft. He was signed by the San Diego Chargers on December 26, 2012. Miller played in 46 games with 34 starts, compiling 64 receptions for 774 yards and five touchdowns.
