Koehler is available from the bullpen Monday and won't start Tuesday against the Red Sox, Mike Wilner of Sportsnet 590 The Fan reports.

EDGE Analysis

Koehler had been scheduled to start Tuesday, but the club has decided to send Brett Anderson to the hill instead. At this point in time, it's unclear when Koehler will make his next start for the Blue Jays. Koehler's performance this season has been underwhelming, as his 7.42 ERA and 1.70 WHIP are both career-high marks.
