Olympic champion Jessica Ennis-Hill could make her heptathlon comeback at the end of the month, according to her coach.

Ennis-Hill hasn't competed in a heptathlon since the London Olympics as she recovers from an ankle injury that has forced her out of the start of the season.

Toni Minichiello, coach of Ennis-Hill, is hoping the 27-year old can participate at the Combined Events Challenge in Tallinn, Estonia, on 29 and 30 June.

"That's the plan - we'll go to Tallinn and compete in that heptathlon there," Minichiello told BBC Radio 5 live.

Ennis-Hill has missed the season's first two competitions, pulling out of last Saturday's Women's Athletic League meeting in Edinburgh and Thursday night's Diamond League meeting in Oslo.

With just two months to go until the World Championships in Moscow Ennis-Hill has been advised to rest her ankle.

"She's had a bit of a recurrence of an injury in her ankle. It's not her Achilles tendon, it's the pad that sits underneath the Achilles tendon and that aggravates the tendon and therefore you get a little bit of pain," Minichiello said.

"That's well on its way to mending now, so we're much happier with how it's reacting."

Minichiello is confident that the Olympic champion will be fit for Tallinn as long as she doesn't suffer any setbacks.

"Definitely, with the way things are responding at the minute, I don't see that as being a problem."

After the success of the London Olympics, Ennis-Hill decided to miss the indoor season. She aimed to start the outdoor campaign slightly later than usual after her marriage in May but hasn't been able to.

There have been concerns over her fitness ahead of the World Championships but Minichiello insists that the athlete isn't behind her usual schedule.

He added: "I don't think she's behind at all. I think all we've done different this year is we've decided to start the season later.

"She's in really good shape, physically strong in the gym, running well. I don't think we're a million miles away from where we want to be."
