World 100m record holder Asafa Powel is back in full training after injury had hampered his start to the season.

The Jamaican had been sidelined with a chest injury but should now have plenty of time to recover for the Olympics.

The injury occurred during weight training and forced him to rest for a fortnight.

"He's doing fine and we expect him to be 100% in two weeks," said his agent Paul Doyle.

"It's just a case of making up time and shouldn't affect his Olympic build-up."

Powell is the fastest man on the planet after clocking a time of 9.74 seconds last September in Rieti, Italy but he has a reputation of choking on the big stage.

He went into last year's World Championship 100m final as favourite but could only pick up the bronze with Tyson Gay of the USA taking the gold.

Powell has also seen a new rival emerge in the shape of his countryman Usain Bolt who last month in Kingston ran the second-fastest 100m in history in a time of 9.76 seconds.

The two are expected to meet at Jamaica's national championships at the end of June.
