Since his latest knockout victory, at UFC Fight Night in Boston earlier this month, fans of rising UFC featherweight star Conor McGregor have expected announcement of a showdown with Jose Aldo, the division’s champion (and pound-for-pound entrant).

McGregor hoped for the bout to be scheduled in the coming months for Croke Parke, in his native Dublin, Ireland.

But according to McGregor’s coach, John Kavanagh of Straight Blast Gym Dublin, fans may have to wait a bit longer — and may end up stateside.

“It’s not 100% yet,” Kavanagh said to Ivan Yates of Ireland’s Newstalk, when asked if the bout had been confirmed.   “There was talk of a May date. It may actually be later in the year. I get a lot of Tweets and messages, people wanting to book their flights. I would say hold until the UFC makes their announcement.”

Kavanagh described “midsummer” as the most likely scenario, possibly July, in Las Vegas.

According to Kavanagh, the venue of Croke Park is unlikely due to the site requiring events to end at 11 pm. Many of the UFC’s international events are set at odd hours to accommodate North American audiences. For example, last weekend’s UFC on FOX event from Stockholm, Sweden ended in the early morning hours, local time.

But he’s hopeful for an event there in the future.

“We’re hoping to go over there and win the belt,” Kavanagh said. “And, twist their arm a little bit more and get the first defense in Dublin.”
