The following is from WWE.com:
As a result of colliding with the steel steps at One Night Stand, the No. 1 contender to Kane’s ECW Championship, Big Show, has been diagnosed with a fracture of the sinus cavity and possibly his orbital bone. The 7-foot, 440-pound Singapore Cane Match winner will see a specialist tomorrow in Los Angeles for further examination. Stay tuned to WWE.com for further updates.
Big Show is still expected to be ready to compete at Night of Champions on June 29.
