Bradford Bulls hooker Heath L'Estrange will miss the rest of the season with a knee injury, according to the BBC. The 26-year-old, who signed a new contract at the club last week, has been ruled out for the remainder of the campaign after rupturing his anterior cruciate ligament in Sunday's game against St Helens. L'Estrange was forced off the field during the match. A visit to specialist Professor Steve Boll yesterday afternoon confirmed the worst fears of the player and his club. Bulls coach Mick Potter remained upbeat about L'Estrange's future. He said: "He will get all the help he needs through his rehabilitation. "His character will help him overcome this injury and come back stronger."
