Blue Jays manager John Schneider said Friday that it "would be tough" for Bieber (shoulder) to return from the 15-day injured list before the end of the regular season, Hazel Mae of Sportsnet reports.
Bieber is scheduled to throw a side session Saturday, and the Blue Jays are hoping that the veteran right-hander can return if the team qualifies for the playoffs. Bieber continues to recover from right teres major inflammation that landed him on the 15-day injured list in late August.
