Nova left Friday night’s game against Toronto because of tightness in his right triceps.
“Hopefully, he can knock it out fairly quickly,” manager Joe Girardi said.
Cervelli exited with a broken right hand and is expected to miss at least six weeks. Cervelli and Nova joined All-Star teammates Derek Jeter, Alex Rodriguez, Curtis Granderson and Mark Teixiera on the sidelines.
The Yankees recalled catcher Austin Romine from Triple-A Scranton/Wilkes-Barre and also signed and selected lefty reliever Vidal Nuno from their top minor league team. Jeter, out until after the All-Star game because of an injured ankle, was transferred to the 60-day DL.
“Our hope is that he’s OK,” Girardi said.
There had been an initial report Nova had pain in his elbow when he left after the second batter in the third inning. Girardi said that wasn’t the case and that he thought the right-hander wouldn’t need extra time to recover.
“That’s going to heal,” Girardi said.
Catcher Chris Stewart started Saturday night against the Blue Jays.
Romine made his big league debut with the Yankees in 2011. He spent last year in the minors while rehabbing a strained lower back. He was hitting .333 with one homer and four RBIs in Triple-A this year.
“He’s going to catch some,” Girardi said.
