Merchant says he was diagnosed with vertigo, but after receiving treatment, he was sprung from the hospital after just a few days. He's now recovering at home, and he says he's doing well.
According to WebMD, "Vertigo is a sensation of feeling off balance. If you have these dizzy spells, you might feel like you are spinning or that the world around you is spinning."
Merchant says he "appreciated the outpouring" of support, and even joked it was like witnessing his funeral.
Merchant, who worked alongside fellow greats like Jim Lampley, George Foreman, Roy Jones Jr., and Harold Lederman, laid down his microphone in 2012 ... and is widely regarded as one of the greatest commentators in the history of the sport.
