Concern over the Rangers’ calamitous 1-4 getaway is now at least matched by apprehension over the health of Rick Nash, who on Monday was still feeling symptoms from the blow to the head he took from Brad Stuart last Tuesday in San Jose.

The winger, who has missed two games with his second concussion in eight months, is sidelined indefinitely. Nash, who was placed on injured reserve in a move that opens a roster spot if needed, will not play Wednesday night in Washington and is doubtful at best for Saturday’s match in New Jersey. The Blueshirts then do not play until Oct. 24 in Philadelphia.

“He’s still feeling some symptoms so until I hear otherwise I don’t expect him back,” coach Alain Vigneault said.

Nash missed four games last season with a concussion he sustained in Boston on Feb. 12 when his head was driven into the glass by Milan Lucic. Big No. 61 complained of a headache in the immediate aftermath of last Tuesday’s game that he left after the first period, the head shot from Stuart delivered 2:30 into the match.

The Rangers, who placed backup netminder Martin Biron and 13th forward Arron Asham on waivers on Monday, announced the recalls of winger J.T, Miler and goaltender Cam Talbot prior to Tuesday’s practice.

Miller, who opened the season with the Blueshirts, scored four goals in four games with the AHL Wolf Pack following his surprising, if not unaccountable, demotion following the opener in Phoenix.

Miller will most likely join the third line with Brian Boyle and Taylor Pyatt while freshman Jesper Fast is bumped down to the fourth unit with Dominic Moore and Derek Dorsett. There’s also a chance the 21-year-old could replace Benoit Pouliot on the line with Derek Stepan and Mats Zuccarello, but probably not.

“With Nash and [Carl] Hagelin not there, we’re probably going to bring a little more skill to the team,” Vigneault said before management reviewed its options and made the call to bring back Miller, but not Chris Kreider, as well.

Hagelin, who is on the long-term injury list as he recovers from offseason surgery to repair a torn labrum, is not eligible to return until the Rangers’ 11th game, Oct. 29 against the Islanders.

The winger, who remained in New York during the team’s opening trip, has not yet been cleared for contact. He is scheduled to undergo an exam within the next couple of days.

“It’s progressing the way it’s supposed to,” Hagelin said after participating in practice while wearing a non-contact jersey. “I’ve been able to do a lot more work in the gym in addition to skating while the team was away.”

Asham, meanwhile, is likely at the end of his NHL road after a career encompassing 785 games during which he has accumulated 1,004 penalty minutes. The 35-year-old hard-nosed competitor and long-time policeman played three games this year, acknowledging he was “fighting for my NHL career,” after having cleared waivers in June.

“That’s the way she goes,” said Asham, who was scratched on Saturday in St. Louis in favor of seventh defenseman Justin Falk after also having sat out the opener. “It’s a business. There are no hard feelings.”

Asham is in the second year of a two-year contract worth $1 million per. He will carry a $75,000 cap hit if, as expected, he clears waivers and is assigned to the Wolf Pack.

“I hope somebody picks me up but if not, I’ll go down and play hard,” he said. “I’m going to play my game the way I always do.

“I’ll figure out what happens with the family [living on Long Island] first,” Asham said. “Obviously I’m disappointed, but I was expecting it some time.

“I’m getting old.”
