The television network "TNT" reported today, Monday, that Shaquille O'Neal, who has previously been inducted into the Hall of Fame, underwent surgery on his upper thigh after the four-time NBA champion alarmed fans by posting a photo of himself lying on a hospital bed. The 15-time All-Star and analyst for "Inside the NBA" will be absent from the broadcast unit during his recovery but sent a message of support to sports broadcaster Ernie Johnson and his colleague Candace Parker, the duo who accompany him on the show, yesterday, Sunday. O'Neal (51 years old) wrote on Twitter: "I always watch the show, I miss you all," along with a photo of himself in a hospital gown. Parker, a WNBA All-Star, responded to O'Neal's tweet saying, "Love you big fella," amid fan speculation about his health. A spokesperson for "TNT" confirmed to Reuters that O'Neal did indeed undergo surgery.
