MILWAUKEE -- Cubs Minor League pitcher C.J. Edwards, ranked No. 4 on MLB.com's Cubs' Top 20 Prospects list, underwent an MRI on Friday, which revealed some fatigue and inflammation in his right shoulder. The good news is there was no structural damage.
Edwards, 22, was examined in Chicago on Friday. He posted on his Twitter account: "Great news today rest then back at again #cubs#smokies#stilllivingmydream."
Cubs manager Rick Renteria said Edwards will begin a throwing program in a couple weeks.
"He's obviously somebody we really like, and this is just a little setback and he'll be fine," Renteria said.
The right-hander had a 2.61 ERA in four starts for Double-A Tennessee. On Sunday, he gave up two runs on three hits and two walks over six innings against Birmingham. Edwards felt some discomfort in his shoulder during a side session.
The slender right-hander was one of four players acquired from the Rangers for Matt Garza last July.
Edwards made one start in Spring Training for the Cubs and gave up three runs on four hits and three walks over 2 2/3 innings.
