Burke was placed on the 7-day minor-league injured list with a blister on his left hand Thursday, retroactive to Sept. 22, Levi Weaver of The Athletic reports.
Burke allowed no hits and a walk while striking out three in four scoreless innings during his last appearance at Triple-A Round Rock, but he apparently developed a blister that will force him to miss his next turn through the rotation. Whether he's cleared to return prior to the end of the regular season remains to be seen.
