Mets leftfielder Michael Cuddyer will undergo an MRI exam Wednesday on the sore left knee that forced him out Tuesday night's 1-0 loss to the Cubs.

"I'm definitely concerned but I don't want to jump to conclusions," said Cuddyer, who was replaced in the seventh by Darrel Ceciliani.

Cuddyer said he sustained the injury in the first inning while running out a grounder. The tightness in his knee only worsened until he was forced to leave.

"As the game progressed, it progressively got tighter to the point where I had to say something," he said.

Cuddyer, 36, signed a two-year, $21-million deal last winter. But after going 0-for-2 against the Cubs, he's hitting only .243 with six home runs and 28 RBIs.

"He didn't feel like he could run on it," manager Terry Collins said. "We'll just see what the doctors say tomorrow."

Biding his time

Jenrry Mejia isn't eligible to return from his suspension until July 7. But according to Collins, reports indicate the former closer is ready to rejoin the bullpen.

Mejia is wrapping up an 80-game PED suspension with a rehab stint in Las Vegas. Collins said his fastball has been clocked in the 94-96-mph range.

Extra bases

Catcher Travis d'Arnaud is wearing a brace to restrict the mobility in his strained left elbow. He's on the disabled list retroactive to June 21. Collins said there is no timetable for his return . . . Cubs manger Joe Maddon chose Whitestone native and former Met Mike Baxter to take the lineup card to home plate . . . Bobby Parnell tossed a scoreless inning in relief. He has yet to allow a run in 6 2/3 innings since his return from Tommy John surgery.
