Heat is on for Broncos, Cowboys in Mt Isa trial HOT WORK: Tariq Sims and the Cowboys will face sweltering conditions during their first pre-season trial against the Broncos in Mount Isa. THE Broncos and Cowboys will swelter through their first pre-season trial in Mount Isa in temperatures forecast to be high as 37C. With insufficient lighting for a night game at Mount Isa's Alec Inch Oval, the match will be played at 5pm on Saturday. The maximum temperature in Mount Isa yesterday was 40C and the players are expecting the mercury to be 37C at kick-off time. Both teams are prepared for extreme conditions with the trial to be played in quarters. Unlimited rotation of the eight-man interchange bench means players will be unlikely to play more than 50 minutes. Ice vests and two frozen drink machines pumping out Gatorade slurpees will work overtime to help keep players' core body temperatures at safe levels. The Cowboys' halfback spot is Michael Morgan's to lose. Morgan will play five-eighth beside Robert Lui in Saturday's NRL trial but the 20-year-old has the inside running to partner Johnathan Thurston in the halves when the Cowboys start their season on March 9. Morgan's three-try performance against the Broncos in last year's finals is a factor. North Queensland coach Neil Henry wants to see how Morgan and Lui click against the Broncos but said Morgan was the man to beat. "I think Michael Morgan's got the right to sit there on the back of his performances last season," Henry said. He was tremendous. He finished the season in a strong position. But Lui can make that decision tougher for Henry as he returns from exile. It will be Lui's first game since round 1 last season after he was suspended by the NRL following a domestic violence conviction. The Cowboys tried unsuccessfully to have the ban overturned and he spent the rest of last season doing community work for the club and training in opposition to the team's halves. Winger Denan Kemp has been named to play his first match for the Broncos since 2010. Kemp is back after unsuccessful stints in rugby union and with the Dragons and will start on the end of a young backline. Utility Ben Hunt will wear the No.7 jumper and captain a side featuring Luke Capewell at five-eighth, Lachlan Maranta and Jordan Kahu in the centres and Scott Anderson and Dunamis Lui as the props.
