Flair will be going to the hospital today for testing, reports PWInsider.com.
Ric was scheduled to be involved in the Cena/Rock main event segment last night on Raw, taking Booker T's spot at the guest panel table.
Another interesting point to note is that WWE apparently had further plans for Ric Flair originally as he was scheduled for three Raw appearances heading into WrestleMania 29. PWInsider.com reports that Flair was booked for last week's Raw in Pittsburgh, last night in Philly, and even next week's edition in Washington, DC.
There's been no reason given for his absence last week, and it hasn't been said yet whether or not he'll appear on next week's go-home edition
