Chicago Cubs pitcher Justin Steele is set for season-ending surgery to address a significant flexor tendon injury in his left elbow, raising concerns for his future after previously undergoing Tommy John surgery. Manager Craig Counsell expressed his support for Steele, noting his positive attitude despite the setback. The Cubs will temporarily fill Steele's rotation slot with Colin Rea, while Javier Assad, currently rehabbing, is a potential candidate for the rotation upon recovery. Steele's performance in the past two seasons showcased his development, though this injury comes as a serious blow to the Cubs’ pitching plans.
