Update (7:35 p.m. ET): Mike Johnson of PWInsider.com is reporting that Flair was taken to the hopsital due to a blood clot. Flair suffered a blood clot not long ago during an appearance overseas in Japan.
To update on an earlier report stating that Ric Flair and Bret Hart would be part of tonight's 3/25 WWE RAW in Philadelphia, Dave Meltzer is reporting that Flair was at the building today and described as "not looking healthy." Flair was taken to a local hospital and has already left Philadelphia for a hospital in Charlotte closer to his home.
With Flair no longer being scheduled to be part of the show, Hart along with Dusty Rhodes, Jerry Lawler and Mick Foley are scheduled to be part of a segment tonight involving WWE Champion The Rock and John Cena.
