Rays Manager Joe Maddon said after a 7-3 loss to the Kansas City Royals that the team was still awaiting results from another series of tests. Moore was getting a second opinion from Andrews after an MRI exam performed in Kansas City proved to be inconclusive.
Maddon did say that it appears the ligaments in Moore's elbow were not fully torn. If that were the case, season-ending surgery would be a foregone conclusion.
The Seattle Mariners will be without left-hander James Paxton because he was put on the 15-day disabled list because of a strained muscle on the left side of his back.
Seattle announced the move after an MRI exam confirmed the original diagnosis.
Paxton left Tuesday night's win over the Angels in the sixth inning after feeling a twinge in the muscle. Paxton got the win, retiring 14 batters in a row during one stretch to improve to 2-0.
