Steven Matz is unlikely to be ready for Opening Day because of tenderness in his left elbow, the New York Mets have announced.

"He's being examined today," Collins said Wednesday. "We should know more, but we don't plan on having him pitch the next few days."

Matz is expected to have an MRI. The left-hander threw on the side on Monday and Tuesday and was still feeling pain.

"Nothing's changed over the last couple of days," Collins said. "It's just that the last two days he played catch, and he still feels it, so we thought it would be important to have him looked at."

Matz was projected to be New York's No. 5 starter.
