In late December, Saints coach Sean Payton said that running back Reggie Bush had arthroscopic surgery to help repair the left knee injury that forced him onto injured reserve. That wasn’t true, however, and G.M. Mickey Loomis has admitted that Bush had microfracture surgery. Despite the more serious surgery, Loomis said that the team still expects him to be ready for training camp. “I wouldn’t want to call it minor, because he’s got a pretty significant period of rehab time,” Loomis said. “But at the end of it, he shouldn’t have any issues.” Recoveries from microfracture surgery have been a mixed bag for NFL players. Kellen Winslow had the surgery in February 2007 and posted great numbers during the 2007 season, but Terrell Davis never played again after having the procedure. Like Davis, Bush has some issues with the underlying health of his knee, which may impact how quickly he can recover. Bush tore the PCL in his left knee in 2007 and then tore the meniscus this season, which required arthroscopic surgery. Bush ran for 404 yards, caught 52 passes for 440 yards and scored nine touchdowns in 10 games this season.
