Bush said that he may "possibly" throw a bullpen session Sunday, Sam Butler of MLB.com reports.

EDGE Analysis

The Rangers have been down two key relievers of late in Bush and Keone Kela (shoulder), though the latter appears closer of the two to return from the disabled list after tossing a 25-pitch bullpen session Friday. Bush, who hit the DL after suffering a concussion and right MCL sprain in an Aug. 20 collision with teammate Joey Gallo, is no longer feeling the effects of the concussion but still needs more time for the knee to heal.
