Matz is expected to be placed on the 10-day disabled list, Matt Ehalt of The Record reports.

EDGE Analysis

It's unclear what Matz is dealing with at this point, but the issue is apparently serious enough to warrant a trip to the disabled list. He went to the doctor to be examined Monday, according to Mike Puma of the New York Post, and more should be known once the results of his visit are disclosed. This may help explain his poor performance last week, where he conceded seven runs (six earned) in just 3.1 innings. Tommy Milone is expected to take his place in the rotation while he's sidelined, starting Tuesday against the Diamondbacks.
