Cowell's five-hour surgery included "a number of fusions" and the insertion of a "metal rod," the report says. The former American Idol judge's rep had earlier stated that Cowell was "doing fine" in the aftermath of the injury, and that the Sunday surgery was scheduled the day prior.

However, doctors have also reportedly told Cowell that he's "lucky" despite the severity of his back injury. Cowell is believed to have fallen from the bike onto his back while testing it at his home with partner Lauren Silverman.
