Atlanta Falcons wide receiver Rondale Moore will miss the season with a knee injury after the team placed him on injured reserve on Thursday.

Moore was carted off the practice field with his right leg immobilized in an air cast near the end of a joint practice with the Miami Dolphins on Wednesday.

The Falcons immediately ended practice, informing players Moore was being taken to a local hospital in the Miami Gardens, Fla., area.

The injury occurred during the 11-on-11 practice period. With all the action directed toward the right corner of the end zone, Moore collapsed in the opposite corner, where he was tended to by doctors and trainers.

“It’s heartbreaking,” veteran defensive lineman Grady Jarrett said after practice. “Not much of a heartbreak like it.”

Moore, 24, played collegiately at Purdue and was selected by the Arizona Cardinals in the second round (No. 49 overall) of the 2021 NFL Draft. The 5-foot-7 receiver has contributed in the NFL, gaining a career-high 503 all-purpose yards with two touchdowns in 17 games (eight starts) last season with the Cardinals.

He has 135 receptions for 1,201 yards and three TDs in 39 games (23 starts) for the Cardinals.

The Cardinals traded Moore to the Falcons in March for quarterback Desmond Ridder.

In a corresponding move on Thursday, the Falcons signed rookie punter Ryan Sanborn. He played 56 games at Stanford (2019-22) and Texas (2023) and punted 232 times for a 42.3-yard average with a long of 68 yards. He also had 79 punts downed inside the 20-yard line.
