SPARTA, Kentucky -- Brad Keselowski's victory lane celebration at Kentucky Speedway on Saturday night was briefly interrupted when he had to make a trip to the track's infield medical care center.

While celebrating his second win of the season, Keselowski, the 2012 Sprint Cup champion, cut his right hand while opening a champagne bottle. The bottle exploded in his possession. His laceration required four stitches.

After he received treatment, Keselowski changed his race uniform and then returned to victory lane to continue his post-race media obligations.

"We were playing around with some champagne bottles, and as I told my good friend, 'We should have stuck with beer.' We were having too much fun with champagne, and one of the bottles broke, and I cut my hand open. It's no big deal," Keselowski said.

Keselowski had perhaps his most dominant performance ever in a Sprint Cup race. The Team Penske driver started on the pole and led 199 of 267 laps. It was the second time he won at Kentucky.

"Welcome to the party," Keselowski said in victory lane after he returned from the infield medical care center. "It's all good. I'm just glad we won. It's a lot better story when you win and get hurt."

Joey Logano, who finished ninth, poked fun at Keselowski, his teammate, on Twitter after hearing about his injury.
