Philadelphia Phillies manager Rob Thomson provided an injury update on Aaron Nola before Tuesday’s game against the Chicago Cubs. “He’s got a stress reaction on his right rib,” Thomson revealed. “He’s no throw for 2 weeks.”

Aaron Nola MRI results reveal rib stress reaction

According to Thomson, an MRI showed the injury. There is no apparent cause. “He doesn’t really remember the moment that it happened,” said Thomson. “He just woke up one day, and it was sore.”

The new injury comes as Nola was already on the Injured List with a minor sprained ankle. Originally, an illness had set Nola back, and now, he won’t be ready for at least another month.

Nola had been struggling for the majority of 2025 before going on the IL. He was 1-7 with a 6.16 ERA in 9 starts. He looked to be turning things around, but was shelled for 9 runs against St. Louis in his last start.

“He wants to play. He wants to pitch. He wants to help us win,” said Thomson when asked how frustrating this was for Nola.

Nola was a durable mainstay in the Phillies’ rotation for years. He had topped 190 IP all but twice since 2018. This will be Aaron Nola’s longest IL stint since 2017. Since 2018, he has been a pillar of health and longevity.

Tuesday’s starter, Mick Abel, will have a longer stay in the Phillies’ rotation as a result of the injury. Thomson has liked what he’s seen from the 23-year-old rookie. “His poise and composure is fantastic,” said Thomson. He praised Abel’s “strike-throwing ability” and his ability “to spin the baseball and spin it for strikes”.

In 11.1 IP, Abel has allowed a single earned run and has yet to surrender a walk. In his major league debut, he tied Curt Simmons for the Phillies club record for strikeouts in a debut with 9.
