Royals pitcher Tim Collins is scheduled to undergo an MRI on his sore elbow Thursday, according to MLB.com. 

Collins left Wednesday's game against the Rangers after experiencing tightness in his elbow. Kansas City won the game 13-2. Though further testing will take place, Collins expressed optimism about the injury. 

"I think it's just spring training," Collins said. "Everybody goes through this. It's just some tightness. I don't know what the plan is yet with the trainers."
