With Rick Nash iffy for tonight’s game against the Capitals in Washington, the Rangers recalled rookie Chris Kreider from Connecticut of the American Hockey League just one day after sending him there.

Nash missed a season ticket-holder event Friday night at the Beacon Theatre, with the Rangers saying he was sick. He did not practice yesterday.

“It’s just a body maintenance day,” coach John Tortorella said. “Yeah, he’s played a lot of hockey.”

Nash has played in all 13 of the Rangers’ games this season, so if he’s too sick to go tonight, he will miss his first game since joining the Blueshirts in the offseason.

It also is worth noting Nash’s head was rammed into the boards during Tuesday’s game on a check from the Bruins’ Milan Lucic. He did play Thursday against the Islanders, however.

At practice yesterday, Nash’s spot on the first line, with Derek Stepan and Carl Hagelin, was taken by Stu Bickel.
