Atlanta transferred Riley (abdomen) from the 10-day injured list to the 60-day IL on Monday.
The transaction frees a spot on the 40-man roster for the addition of Ha-Seong Kim (back), who was claimed off waivers from the Rays on Monday. Riley underwent season-ending core surgery nearly two weeks ago and is expected to be ready for spring training.
Braves' Austin Riley: Undergoes season-ending surgery
Rotowire
Atlanta announced Thursday that Riley (abdomen) underwent season-ending core injury surgery.
Riley is expected to be ready for the start of spring training in February. The third baseman has been out since Aug. 2 and had been experiencing soreness in his abdominal area, and he was rehabbing to play again this year before suffering a setback this week. With surgery now in the rearview mirror, Riley's 2025 season is officially over, and he finished with a .260/.309/.428 slash line, 16 home runs, 54 RBI, 54 runs scored, two stolen bases and a 27:128 BB:K across 447 plate appearances. Now that he's done for the year, Riley will have missed a total of 112 games over the past two seasons.
Braves' Austin Riley: Return delayed due to soreness
Rotowire
Riley (abdomen) felt more soreness during a workout Tuesday and is not expected to be activated from the 10-day injured list anytime soon, Gabe Burns of The Atlanta Journal-Constitution reports.
Riley has been sidelined for most of August with a strained lower abdominal muscle and continues to feel discomfort each time he attempts to ramp up activities. With Atlanta out of playoff contention, the club has little incentive to push its third baseman back onto the active roster. Consider Riley out indefinitely. Nacho Alvarez will continue to occupy the hot corner in Riley's absence.

Braves' Austin Riley: Not expected to need rehab stint
Rotowire
Riley (abdomen) likely won't need a rehab assignment before rejoining Atlanta's lineup, David O'Brien of The Athletic reports.
Manager Brian Snitker wouldn't offer a guess as to when the third baseman might be activated from the IL, but Riley's not expected to be too far behind Ronald Acuna (calf), who should rejoin the lineup before the end of the week. Riley has been sidelined since Aug. 2 after aggravating an abdominal strain that had previously cost him eight games sandwiched around the All-Star break. It's been a disappointing season overall for the 28-year-old, whose .737 OPS would be his lowest mark since he became a full-time player in 2021.
