Paxton (elbow) is expected to throw a bullpen session Thursday, Greg Johns of MLB.com reports.

EDGE Analysis

The M's were forced to make a DL move with Paxton on Tuesday (retroactive to Aug. 8), but if he makes it through Thursday's bullpen and a subsequent live session, he should return next week shortly after his 15 days are up. Cody Martin will serve as Seattle's fifth starter on a temporary basis.
