Yordano Ventura was suddenly pulled from Monday's start for the Kansas City Royals because of lateral elbow discomfort.

Ventura will undergo an MRI on Tuesday to determine the extent of the problem.

"I'm not concerned it's a ligament injury," Ned Yost said. "The trainers were right on it, and they came two minutes later and said it's the outside of the elbow, and that's where my concern dropped way off."

Ventura has a 3.45 ERA, 1.26 WHIP and 59 strikeouts in 57.1 innings this season.
