Yordano Ventura diagnosed with valgus stress overload

Royals manager Ned Yost said during the team's television broadcast Tuesday that pitcher Yordano Ventura is dealing with valgus stress overload, Yahoo! Sports reports.

"Even if on the lateral side, excessive valgus force can lead to cartilage damage, arthritis [and] bone chips," according to the report. "And instability leaves [the] UCL prone."

The MRI on Ventura's elbow came back clean earlier Tuesday, and he is expected to miss just one start. However, the new development could lead to further issues down the road.
