Chris Sale's awful season just got a whole lot worse ... the Boston Red Sox revealed on Tuesday he suffered a broken wrist in a bike accident over the weekend and is now done for the rest of the year.
Sale -- who was nursing a finger injury that he sustained after taking a line drive off his hand on July 17 -- had been riding his bike on Aug. 6 when the accident happened, according to the team.
The 33-year-old was diagnosed with a "right distal radius fracture" .
