Bolt to appear in Oslo

The Diamond League meeting is the Jamaican's first confirmed appearance of the 2011 season following his struggles with an Achilles injury last year.

The 24-year-old hopes to defend his 100m and 200m world titles this summer and he believes meeting like the Bislett Games will prepare him for the championships in South Korea.

"As this is a World Championship year, every meet is important to me in my build-up to defending my titles," Bolt said.

"My preparations have gone really well, the injury problem I had during the summer is fully healed and my training has gone according to plan.

"My competition at Bislett and several other Diamond League meets throughout the season will be an important stepping stone towards that goal."
