Angels' Robert Stephenson Sidelined Indefinitely with Stretched Biceps Nerve

Los Angeles Angels reliever Robert Stephenson has been diagnosed with a stretched biceps nerve in his surgically repaired right elbow, an injury that will sideline him indefinitely despite MRI tests showing no structural damage. Stephenson, who signed a three-year, $33 million deal in January 2024 and missed all of the previous season due to Tommy John surgery, returned to pitching with a perfect inning on May 28 but experienced discomfort leading to his removal from a game two days later. The injury is considered unusual and tricky to treat, with doctors noting its rarity and limited treatment options. Stephenson expressed frustration but remains hopeful as medical staff are not overly concerned, though the timeline for recovery remains uncertain. The Angels have placed him on the injured list and are cautious with his return, as their bullpen requires reliable arms. Meanwhile, pitching prospect Sam Aldegheri briefly replaced Stephenson but has since been sent back to Double-A to make roster space for another returning player.
