Jessica Ennis faces a testing rematch with Olympic champion Nataliya Dobrynska after the Ukrainian confirmed her participation in next month’s World Indoor Championships in Doha.

Ennis defeated Dobrynska to take the world heptathlon title in Berlin last summer and will be looking for a repeat performance as the pair compete for the indoor pentathlon crown.
It will be the third time Dobrynska has taken part at the World Indoors following her silver medal in 2004 and her fourth place in 2008. The pentathlon is limited to just eight athletes, six of whom are invited based on their 2009 outdoor performances.

Ennis, 24, will be making her debut in the event but looks to be in the form of her life after setting a British record of 7.95sec in the 60m hurdles and a high jump personal best of 1.94m in Glasgow last Saturday.
Meanwhile, Mark Lewis-Francis will go head to head with former GB team-mate Dwain Chambers when the pair contest the 60m at the Birmingham Games tomorrow.

Lewis-Francis, the 4x100m gold medallist from the 2004 Athens Olympics, has already signalled a return to form after serious injury by running 6.59sec at last week’s London Games — his fastest indoor time for five years.
