BALTIMORE – Carter Camper scored the pivotal goal in a shootout, and the Boston Bruins rallied to beat the Washington Capitals 3-2 in a preseason game Tuesday night.

The Bruins (2-0) trailed 2-0 late in the second period before coming back. Camper’s goal, in the eighth round, ended the game.

Justin Florek and Chris Kelly had goals for Boston in regulation. Florek scored in the final minute of the second period and Kelly tied it at 7:53 of the third.

Tom Wilson and Casey Wellman scored for Washington, and Braden Holtby stopped all 12 shots he faced in 30 minutes. It was the third straight shootout for the Capitals (2-0-1).

It was the second time in three years the Capitals played a preseason game in Baltimore. A pane of glass fell and broke on the ice after Washington’s Alex Ovechkin and Boston defenseman Chris Castro collided in the corner with 4 minutes left in the second.

Both teams skated off, and the final 4 minutes were played immediately before the third period.

NOTES

PANTHERS: Declaring himself “reborn” after more than a year off, Tim Thomas was back on NHL ice Tuesday, working out with the Florida Panthers for the first time since agreeing to a tryout deal with the club.

The goaltender with two Vezina Trophies and a Stanley Cup will accompany the Panthers starting Wednesday for their three-game, four-day trip to Dallas, San Antonio and Tampa, Fla.

“After 14 years of pro hockey, I got tired and I needed a break,” Thomas said. “Now I’m energized and I’m looking forward to it.”

Thomas came to Florida to compete for a starting job and will only need to beat Jacob Markstrom to win that role. Markstrom has been the Panthers’ goalie of the future for some time and arrived in this camp expecting to finally be the No. 1 guy — especially with veteran Scott Clemmensen recovering from knee surgery that may keep him off the ice until next month.

Markstrom didn’t seem bothered in any way by Thomas’ arrival.

“It’s the best league in the world,” Markstrom said. “It’s not supposed to be easy.”

In parts of eight NHL seasons, Thomas has a 2.48 goals-against average, stopping just over 92 percent of the shots he has faced. “Mentally and physically, he’s very strong and he’s ready to compete for a starting position here,” said GM Dale Tallon.

BLACKHAWKS: Chicago’s lineup Tuesday included 14 members of the championship team, but captain Jonathan Toews sat out with a lower body injury.

RED WINGS: Forward Johan Franzen had been scheduled to play on a line with newcomers Daniel Alfredsson and Stephen Weiss, but missed the game at Chicago due to a sore hip flexor.
