Mick Halford is set to run both Opera Gloves and Certerach in Friday evening's Group Three Diamond Stakes at Dundalk.

Certerach picked up some good place money in Dubai earlier in the year and only had his first run back in Ireland in the Irish St Leger last month.

Opera Gloves, owned by Sheikh Mohammed, was a close second to Aidan O'Brien's classy filly Venus De Milo in a Listed race at Naas in June and after a couple of below-par runs, she won at Killarney last time out.

"I think both Opera Gloves and Certerach will run," said Halford.

"Opera Gloves won nicely at Killarney and ever since then we've been waiting for this race for her as she won her maiden at Dundalk. She's in good form.

"With Certerach, he was just having his first run back in the Leger the other day and he looked a bit rusty and got quite tired.

"He's a course and distance winner though, and he's come forward a good deal since then.

"The plan is to head back out to Dubai with him."
