Lucas Duda left Friday night’s game in the seventh inning with what was then an undisclosed injury.

After the game, Terry Collins said Duda had more back pain, and a decision to place him on the disabled list could come in the next day.

Duda suffered a lumbar strain last week which caused him to miss seven games. He returned to the lineup against the Orioles on Tuesday.

If Duda has to go on the disabled list, perhaps Michael Conforto will survive yet another demotion to the minor leagues. He was optioned to the minor leagues in early August only to be immediately recalled when Kirk Nieuwenhuis landed on the disabled list.

Duda went 1-for-4 with an RBI on Friday night.
