Nathan Cleverly enjoying life in America ahead of light-heavyweight title defence against Shawn Hawk The Welshman, who will face Native American Shawn Hawk at the at the Staples Center in Los Angeles on Saturday night, said: "It was going great in the UK but there were no other challenges left after I wiped the floor with Bellew. I needed to spicethings up in my career and fighting in America is the way forward for me. Cleverly, who is on the brink of unification fights against IBF champion Tavoris Cloud, WBC title holder Chad Dawson, WBA ruler Beibut Shumenov or the legendary Bernard Hopkins if he impresses a big American TV audience this weekend, has been making the most of his time in Los Angeles ahead of his first fight in America. The 25 year-old has been in Los Angeles for almost a week and enjoyed the five-star treatment he has been receiving - he trained in front of a huge media gathering at MacArthur Park, been to visit Mickey Rourke's at the movie star's home and trained at the Wild Card Gym. Cleverly added: "This is the place to be. This is where the graft is done. It is a great place to be in and I am glad I am experiencing the atmosphere here. Meanwhile, Hawk has said he is fighting fit and ready to face Cleverly. Hawk, who was approached as a late replacement for Ryan Coyne just last week, insisted he is always "in shape around the weight limit." I have been preparing like the fight was going to happen and I wouldn't be here if I didn't think I would win. I stay in shape and never weigh more than 180lb so I am always ready to go if the phone rings for a fight. I knew plenty about Nathan and watched tapes of him long before I knew I was going to fight him. He is a good champion. He is fast, tall, throws a lot of punches and reminds me a lot of another great fighter Joe Calzaghe. Hawk has won 23 of his 26 professional contests, and the community in the Crow Creek Sioux Tribe make sure he can box full time. Hawk, 30, added: "Right now there are no Native American boxers successful at the highest level and I want to make my community proud on Saturday night." Cleverly v Hawk will be shown live and exclusive in the UK on BoxNation (Sky 437/Virgin546) from 1am Sunday. Join at boxnation.com.
