Saturday's third round - the last 48 stage - is regarded as one of the nights of the year, as eight heats over 480 metres see the fastest greyhounds in Britain and Ireland aim for a place in Tuesday's quarter-finals. The first three in each heat qualify.

Surely one for Ireland. The battle for early pace will be between crack Irish pair Kereight King and Droopys Jet, plus the bitch Skate On, but can Jet overcome a tough trap six draw? The race might be set up for the powerhouses TYRUR SUGAR RAY and Teejays Bluehawk. The race of the round?
Red-hot favourite here is the brilliant BALLYMAC VIC. He's a dog with all-round speed, but he moves wide early and could give those inside every chance. Realistically it's about who will finish second, and Ringtown Snowy and Priceless Pilot will be flashing home. Pilot flies late on!
SHANEBOY SPENCER has superb early pace and a vacant trap outside him to help. His battle with that terrific front-running bitch Droopys Loner will be key. But both will be watching for the big, big finish of the powerful Farloe Tango.
SIDAZ JACK represents the man they call the Derby King, Charlie Lister. Jack is the least experienced runner in the field but is getting better and is well drawn. Fermoy Henry will be no pushover as he starts well, while Airlie Impact will be running on strongly, but keeping very wide.
Benkaat Blue was just touched off in the second round but could again lead these a merry dance. However, so too can BOHERNA RUMBLE who has been pacing up well. Hather George has form over further so will not be stopping if the leaders crowd up.
Enter the stage the Derby favourite BALYMACE ESKE. A big odds-on chance, he has the draw in one who keep clear of trouble as he bids to add the English Derby to his Scottish Derby crown. Expect a flyer here from both Stonepark Crash and Loughteen Blanco. Droopys Ed Moses has a huge finish.
Eske's kennelmate at Barrie Draper's range is FARLOE WARHAWK and he won the Puppy Derby here last year. He must clear Newinn Rocket early who is running well. Screen Critic and Jaytee Hellcat are both big runners here on the clock in what looks one of the most competitive heats.
SHANEBOY ALLEY won the big Sky race at Swindon, the Arc, and his great early speed could soon have him clear. However, Garryglass Rodge and Bittles Bar are also lightning starters. But all of these will be watching Holden Spy, who tears down the back straight and will challenge off the last bend.
