Rangers' Shanahan out of hospital day after on-ice KO

"We'll rely on (the neurologist) and follow the appropriate instructions. So far it's much better."

Knuble broke the orbital bone and cheekbone on the right side of his face in the violent collision. He will undergo surgery in the next few days once swelling decreases.

Shanahan showed no other serious injuries other than the concussion, but is experiencing overall soreness.

"He's got a bit of a bruised shoulder, that's about it," Renney said. "It's like a car accident -- everything hurts."

Shanahan, who leads the club with 28 goals in his first season in New York, delivered a simple message. He wanted his teammates to know he was thinking about them, and he gave them good luck wishes -- expressing his desire to rejoin them quickly.

"He said thank you for all the phone calls he got from the guys, but he didn't remember who called," goalie Henrik Lundqvist said. "It was just good to see him smiling."

The Rangers didn't immediately make any roster moves, but Renney said Shanahan would be placed on the injured list -- keeping him out at least seven days.

New York also lost defenseman Marek Malik during Saturday's game when he reinjured his left shoulder. Malik, who missed three games earlier this month, was to be examined Sunday at Madison Square Garden.

The only bright spot for the Rangers was the return of Lundqvist. He was felled early in the second period Saturday when a hard slap shot struck him in the left shoulder in an area not protected by padding.

He finished the period, but sat out the third as Renney rested him because of the back-to-back games.

After a night of icing the shoulder, Lundqvist made 21 saves for his 25th victory of the season.

"I wanted to get in right away and get a win," he said. "I know it's no problem, it's just pain."

Every contest is critical for the Rangers, who are fighting to make a second straight postseason appearance. New York entered Sunday's game in 11th place in the Eastern Conference, three places and five points below the playoff cutoff.
