4:33 pm: Matz told reporters that an impingement in his shoulder is causing discomfort. That said, he said he expects to pitch again this season, it just won't be Thursday.
4:25 pm: Terry Collins said Tuesday, although there is no structural damage in his pitching shoulder, Matz again experienced continued tightness and stiffness while throwing during a bullpen session earlier this week.
Collins admitted to being concerned that Matz could miss the rest of the season.
DeGrom, who was originally scheduled to start Monday, but delayed to Friday to get extra days off between starts, will now start Thursday in place of Matz.
Previous Reports and Reaction
Matz was put on the disbaled list retroactive to August 15. He was diagnosed with a mild shoulder strain and rotator cuff inflammation, but no structural damange to his left shoulder, the team later announced.
In his last start, Matz allowed only one hit in 7 1/3 scoreless innings against the Padres. He has been pitching with a bone spur in his left elbow since at least June. He has been receiving shots of painkillers before each start to combat the discomfort, a team source said to the New York Daily News..
According to Collins, pitching coach Dan Warthen sees no evidence that Matz adjusted his mechanics to compensate for elbow pain, which would be one theory why his shoulder may be hurting.
