M4 Monster Suzuki's John Hopkins will undergo surgery on his right wrist tomorrow in an effort to get more movement from his throttle hand."The bike was good, the bike was really good and competely capable of being up at the front and running good," Hopkins said after finishing fifth in yesterday's second AMA Superbike race at Auto Club Speedway in Fontana, California, yesterday. "Physically, I'm handicapped at the moment and it was me, 100 percent, why we couldn't hang at the front. The wrist is just horrible. I have hardly any movement with it and I go down the straigthaway and have to actually roll the throttle and hold on with my finger tips and then let it go and then brake. At the beginning of the weekend, it's fine. When it retracts and contracts, from all the years that I rode with it broken and everything, there's just crazy amounts of scar tissue. The scar tissue actually gets locked between the bones. By the end of the weekend, I have no movement."The surgery will be mostly non evasive and the rehab is expected to be quick with the former MotoGP star not missing any action, including the Road Atlanta National, April 17-18."Five days and I'll be able to motocross," Hopkins said. "I'll get some movement in it and it'll be good. Much better."
