Nimmo (hamstring) suffered a knee injury during his rehab assignment at Triple-A Las Vegas over the weekend, Anthony DiComo of MLB.com reports.

EDGE Analysis

Nimmo has been out since spring training with the hamstring injury and looked to be on the cusp of an activation, but it sounds like the knee issue could delay him further. The Mets likely plan to use Nimmo as a fourth or fifth outfielder once he's activated, meaning he won't be in line for regular at-bats.
