Walker Jenkins, the top prospect in the Twins' minor-league system, has suffered another unfortunate injury setback.

An MRI on Monday revealed that Jenkins has a Grade 2 AC joint sprain in his left shoulder, according to The Athletic's Dan Hayes, who added that Jenkins "will be reevaluated in 10 days to further determine a timeline."

A Grade 2 AC joint sprain typically comes with a recovery of 3-6 weeks, and sometimes longer. Jenkins seems likely to miss at least the rest of May while he recovers, though much of June could also be in danger for the former No. 5 overall pick.
