Matz has been out for nearly three weeks with the injury, and despite the less-than-encouraging news from the doctors, general manager Sandy Alderson did say Matz's lat muscle has improved. Still, he'll go at least another week without picking up a baseball.
Infielder Danny Muno was recalled from Triple-A to take Matz's place on the 25-man roster, ESPN.com reports.
"Based on what the doctors told us there is a very high probability he will be healed in three weeks but that is not guaranteed," Alderson said.
Matz said he felt good enough to pitch in Sunday's game against the Dodgers and the injury did not limit him as he threw six scoreless innings. He added the injury is not painful, but it feels like a pull on the muscle under his armpit.
"It's frustrating, but this is just a minor thing and I will be back," Matz said.
Matz, the No. 33 prospect in the game according to Baseball America, is 2-0 in his first two career starts, posting a sterling 1.32 ERA.
The Mets have since confirmed that Matz was diagnosed with a partial tear of his lat muscle and he will be placed on the disabled list, CBSSports Baseball Inside Jon Heyman reports. The lefty will be shut down for three weeks and then be reevaluated, according to Heyman.
Either Jonathon Niese or Bartolo Colon will start on Sunday in place of Matz.
Matz was nearly unhittable during his time on the hill, striking out eight batters while walking two. He gave up just two hits, both singles, during his 101-pitch outings.
Matz is now 2-0 on the season, and has lowered his ERA on the campaign to 1.32. He continued to be impressive with the bat as well, driving in a run with an RBI groundout.
