In an update on the Mustafa Ali situation, the SmackDown Superstar actually suffered a concussion at Sunday's WWE live event in Ft. Wayne, Indiana, according to Dave Meltzer on Wrestling Observer Radio.
Ali was scheduled to be re-evaluated today at SmackDown in Toledo. If doctors won't clear him to compete, a decision will then be made on who will replace Ali in the Elimination Chamber match for the WWE Title at Sunday's pay-per-view. Ali has reportedly told WWE officials that he's able to work, but they won't wait around and see what happens between now and Sunday, and won't risk it as they will pull him from the Chamber match if he's not cleared today.
Tonight's SmackDown is scheduled to feature a Gauntlet Match to determine who enters the Chamber in the final spot on Sunday. Ali is scheduled to work the Gauntlet with WWE Champion Daniel Bryan, Randy Orton, AJ Styles, Samoa Joe and Jeff Hardy. It's been reported that WWE is planning on blaming Ali's situation on Orton.
There's no word yet on who might replace Ali in the Chamber but speculation is that the spot could go to someone like Rey Mysterio, Andrade, Shinsuke Nakamura or Rusev, depending on who challenges WWE United States Champion R-Truth. Stay tuned for updates on Ali's status for the Chamber.
