Gold Coast Titans' Ashley Harrison facing a month on the sidelines QUEENSLAND stalwart Ashley Harrison is in doubt for the State of Origin opener after suffering ankle and knee injuries in the Gold Coast's loss to Newcastle yesterday. Just five minutes into his 253rd NRL appearance, Harrison was knocked dizzy by a high tackle and buckled under the weight of three Knights. Titans medical staff said the 31-year-old would undergo scans today but the early diagnosis for the 14-game Origin veteran was A grade 1 ankle syndesmosis. He also suffered a twisted knee. If that assessment is correct Harrison will miss about four weeks, meaning he will be touch-and-go for the series opener in Sydney on June 5. He (Harrison) got hit and buckled. When you buckle, you just fall awkwardly," Titans coach John Cartwright said. He lost his bearings and twisted. If you've been knocked out you know what I mean. The knee buckled, ankle buckled and rolled them both. I don't know the extent of it. He'll have to get scanned and we'll know tomorrow. Ashley Harrison leaves the field injured yesterday. Picture: Adam Head The bloke doesn't lie down. If you've got your bearings about you, you're trained how to fall. While Harrison's Origin availability is under a cloud, out-of-favour forward Dave Taylor took a step towards regaining his jersey. After being suspended by the Titans for two weeks for disciplinary reasons, Taylor played 70 minutes in searing conditions. The 24-year-old topped the runs (17) and metres (142) counts for the Titans despite spending the second half at left centre. He was effective. It took a lot to get him down," Cartwright said. He made some nice inroads. It's a bit hard to judge him when he had to play in the centres. That was through necessity more than anything else. NSW star Greg Bird was exhausted after another 80-minute performance and praised his fellow forwards for digging in until the end. It was tough. The boys muscled it out right until the end," he said. Playing in the sun really made it tough as well. We did muscle it out. It wasn't really until the last 10 minutes that it was obvious the Knights were going to win. We kept trying and fighting. It's a cliche but it's a credit to the boys in the middle who had to endure a fair amount of minutes.
