The timeline for recovery is roughly 6-8 months.This is not something uncommon for pitchers since VTOS takes place from repetitive overhead arm movements, but in the case of Wheeler, this resulted in a blood clot that needed to be taken care of for his personal safety.

An upsetting update for the Philadelphia Phillies and their fans: one of the team's star pitchers won't take the mound again this season.

Wheeler was diagnosed with venous thoracic outlet syndrome, and will undergo surgery after having a blood clot removed in his right arm. The expected recovery time is six to eight months.
