Hello George put his injury problems behind him when grinding out victory in the William Hill "High 5" Supporting Greatwood Seniors' Handicap Hurdle at Newbury.After finishing fifth on his return from more than a year on the sidelines at Exeter on New Year's Day, the eight-year-old stepped up on that effort to take his first win since October 2015 in the extended two-and-a-half-mile contest.Moving on past long-time leader Royal Guardsman over the second-last, the 5-2 favourite pulled out plenty under champion jockey Richard Johnson before passing the post 11 lengths clear of Spice Fair.Philip Hobbs, winning trainer, said: "Richard Johnson thinks he probably ought to go further so we might well go three miles next time."He had a tendon problem after winning at Kelso, that's why he had been off for a long time until New Year's Day."He got extremely fat and he would have needed that run (at Exeter). Hopefully he will have a couple more runs over hurdles this season and then go chasing next season."
