Usain Bolt and Asafa Powell will clash in the 100m at the Bislett Games in Oslo on June 7, the pair's second confirmed pre-Olympic sprint showdown.
Olympic champion and world record holder Bolt had already been announced for the Oslo Diamond League meeting in January with his Jamaican teammate confirming his place in the race on Friday.
Bolt and Powell will also meet in the 100m in Rome on May 31.
“These two Jamaicans are the best known personalities in athletics at the moment and we are very proud and excited that they are both coming to Oslo in an Olympic year,” said Oslo meet director Steinar Hoen.
Bolt holds the world record of 9.58sec with Powell's personal best at 9.72.
