TORONTO -- Georges St-Pierre's camp and the UFC are playing down reports that the welterweight champion is hurt.

"GSP has done some sprint training while on holiday. Despite injury report, everything is A-OK, says manager," tweeted Canadian UFC PR director Steve Keogh.

Trainer Firas Zahabi had told MMAFighting.com that St-Pierre suffered an Achilles injury before his March 16 title defence against Nick Diaz.

"I was worried it would tear during the fight," Zahabi was quoted as saying. "We had to cut his last sparring 1/8session 3/8 short due to his injury. He had a week to rest it and then the fight."

St-Pierre won a unanimous decision over Diaz, saying his next move was to go on vacation

The champion was fighting for the second time in four months after a lengthy layoff due to knee reconstruction.

He has said he wants to take some off before facing No. 1 contender Jonny Hendricks.

The UFC, meanwhile, said it was unable to confirm reports that St-Pierre will play Batroc the Leaper, a villain, in the upcoming "Captain America: The Winter Soldier" film, slated for release in April 2014.

St-Pierre's manager did not immediately respond to an email.
