Hull have confirmed Danny Guthrie's tackle on Craig Fagan in Saturday's Premier League match resulted in a broken right leg for the striker. Guthrie's challenge in the final moments of the Tigers' 2-1 victory saw him issued with a straight red card and Fagan left the ground on crutches. The Tigers confirmed on their website that the damage was revealed by an X-ray yesterday morning. The 25-year-old former Derby striker suffered a fractured tibia and the injury is likely to keep him out of action for between six weeks and three months. Tigers manager Phil Brown was scathing about Guthrie's tackle. "It cannot be tolerated, it needs to be kicked out of the game," he said. "When you see that the end product is him putting a fellow pro in a cast, it's just not right. I don't care what is going on at Newcastle, you cannot tolerate this. If I go back to the incident, my players were killing time in the corner, something that every Premier League club does."
