Brantley (shoulder) will undergo season-ending surgery Monday, Ryan Lewis of the Akron Beacon-Journal reports.
Brantley visited with a doctor earlier in the week who confirmed he's dealing with a tear in his biceps. The hope was that rest would be enough to allow Brantley to heal to the point that he could play through the ailment toward the end of the season, but he'll now opt for surgery, ending his 2016 campaign after just 11 major league games. The 29-year-old will turn his attention toward rehabbing in advance of the 2017 season.
