Do Rangers need a backup for the backup?

GREENBURGH, N.Y. -- If Henrik Lundqvist struggles at any point during the Stanley Cup Finals, as he did in Game 5 of the Eastern Conference finals against the Montreal Canadiens, will backup Cam Talbot even be available in relief?

That much remains unclear, as the 26-year-old netminder was absent from practice Sunday at the team's practice facility in Westchester. According to the Rangers he has an "unspecified injury."

After practice, coach Alain Vigneault said that Talbot is "day-to-day" but when pressed further on the issue, he said he did not wish to discuss the situation.

It is not immediately known whether Talbot sustained the injury, or aggravated a pre-existing condition, when he came in for Lundqvist in Game 5 at Bell Centre Tuesday night. Talbot entered the game in the second period after Lundqvist gave up four goals on the first 18 shots he faced.

Talbot surrendered two goals on eight shots during that 7-2 loss. It was his second playoff appearance this spring. He also replaced Lundqvist in Game 6 of the team's first-round series against Philadelphia, stopping all five shots faced from the Flyers.

J.T. Miller, who sustained an upper-body injury in Game 5, skated on his own and is expected to be available at some point of the Stanley Cup Final, maybe even Game 1 on Wednesday.

The Rangers were still awaiting their opponent with the Chicago Blackhawks hosting the Los Angeles Kings in Game 7 Sunday night at the United Center.
