Fortunately for the Tribe, Carlos Carrasco was diagnosed with a mild straight of the right hip flexor. He's officially day-to-day.
"He was squatting and he felt something in his upper leg area," manager Terry Francona said.
The 32-year-old had an MRI on Wednesday and the results were sent to doctors in California.
Carrasco, who battled chronic myeloid leukemia last season, is hoping to return to the starting rotation after making 11 relief appearances last September.
It appears like he's avoided a major injury and is still on track to start the season.
The Indians open spring training against the Reds on Saturday at Goodyear Ballpark in Arizona. The regular season starts on March 26 at Progressive Field.
