Kris Bubic (elbow) will begin a rehab assignment with Triple-A Omaha on Tuesday.

Bubic experienced elbow soreness on May 18th and landed on the injured list. Since he hasn’t missed an extended period of time, he may need to make one or two rehab appearances before rejoining the Royals’ rotation. The 28-year-old has a 4.11 ERA, 1.23 WHIP, and a 51/26 K/BB ratio in 50 1/3 innings this season.
