Regehr in cast after Game 6

CALGARY, Alberta -- The Calgary Flames could be without defenseman Robyn Regehr for Game 7 of the Stanley Cup finals.

According to several reports, Regehr left the Saddledome after Game 6 on Saturday with a cast on his left foot. There was no mention of his injury by coach Darryl Sutter or any of the Flames players. He led all Flames defensemen with 33 minutes and 36 seconds of ice time in their 3-2 double overtime loss, and was on the ice for all 33 seconds of the second overtime.

Regehr's skates will be difficult for the Flames to fill. Besides leading the team in average ice time with 26:37, Regehr is one of the Flames' top hitters and often lines up against the opposition's top forwards.

Richards strikes again for Lightning
Tampa Bay forward Brad Richards has said repeatedly that the Lightning's winning streak when he scores a goal eventually has to come to an end.

If he meant this season, he's only got one game left to be right.

Richards scored twice Saturday, and the Lightning went on to win Game 6 of the Stanley Cup finals against the Calgary Flames 3-2 in double overtime. Game 7 is Monday (ABC, 8 p.m. ET).

The Lightning are now 31-0-2 this season when Richards scores a goal -- 22-0-2 in the regular season, 9-0 in the playoffs.

Richards scored two power-play goals, and he had an assist on Martin St. Louis' game-winning goal. St. Louis, relatively quiet in this series, assisted on Richards' first-period goal.

Richards and St. Louis have now moved ahead of Calgary's Jarome Iginla for the playoff-scoring crown. It's likely that the winner of the Conn Smythe Trophy as the most valuable player in the playoffs will come from that group.

"The first goal, Marty threw it down to me," Richards said. "We had a lot of possession so it was a kind of a jamming play. I was just firing at the net. Dave [Andreychuk] was in front. I was trying to maybe just throw it there and let him whack at it. I think it went off his [Miikka Kiprusoff's] arm and in.

"The second one, Dave and Vinny [Lecavalier] did a good job on the boards, kept it in and I am not sure who it was tried to clear it or pass it, and I just got my stick on it and tried to shoot it right away and that was it."

No-goal no big deal
If there's going to be controversy over a perceived goal by Calgary that could have won the game in regulation, it will not come from the Flames.

Calgary coach Darryl Sutter indicated a puck directed toward the net by Martin Gelinas appeared to be stopped by goalie Nikolai Khabibulin at 13:03 of the third period.

"I looked at it, and that's got to be a conclusive play," Sutter said. "I looked at it from two different angles. And unless they have a different one, you can't say it's a goal. I mean it's so close, but the puck is like this [indicating up on edge] ... I am sure they looked at it."

NHL executive vice president and director of hockey operations Colin Campbell said that the play was reviewed and that only one camera angle showed the puck and "from the angle it was inconclusive whether the puck crossed the goal line. Based on the angle of the image and the fact that the puck was in the air and on edge, there was insufficient evidence that the puck conclusively crossed the goal line."

There was no signal for a goal from the on-ice officials. Normally a review must be conclusive to overturn an on-ice decision.

Several of the Tampa players say they saw the replay on the overhead board and concluded that even if the puck had crossed the goal line, it would have been overturned because Gelinas appeared to make a kicking motion before coming to a stop. Pucks cannot be kicked across the goal line.

Overtime is road time
The Lightning are now 7-0 in games following a loss in the playoffs. Khabibulin has won all seven and has a 0.95 goals-against average, a .963 save percentage and two shutouts in those wins.

The road team is 2-0 in overtime games in the finals this year and 13-4 in the finals in overtime since 1990.
