Rangers' Darvish leaves start with right triceps tightness, to be re-evaluated Friday

The Texas Rangers received an injury scare Thursday.

Starter Yu Darvish lasted only one inning in his first outing of the spring vs. the Kansas City Royals after experiencing tightness in his right triceps.

The Rangers are saying Darvish's removal from the game was precautionary and he'll be re-evaluated Friday.

Darvish threw just 12 pitches in a scoreless first inning, but only one them topped 90 mph.

"I don't think it's anything to worry about," Darvish told reporters after the game.

The right-hander was shut down at the end of last season due to right elbow inflammation.
