Men's Greco-Roman wrestlers compete at 121 pounds (55 kg), 132 pounds (60 kg), 145 1/2 pounds (66 kg), 163 pounds (74 kg), 185 pounds (84 kg), 211 1/2 pounds (96 kg) and 264 1/2 pounds (120 kg).

Gardner has had a series of mishaps and calamities since pulling off his "miracle on the mat" upset of Karelin in Sydney, but now looks to be healthy and a gold medal contender again. Otherwise, U.S. freestyle and Greco-Roman teams don't look especially strong, but Americans could get a medal count boost from a talented four-member women's team. Armen Nazarien (132 pounds, 60 kg) of Bulgaria tries for a third gold and Russian star Bouvaisa Saitiev (163 pounds, 74 kg) looks to rebound from upset in Sydney to American gold medalist Brandon Slay; it was Saitiev's only loss in major international competition since 1995.
