The Elimination Chamber match on Sunday for the WWE Championship will no longer include Mustafa Ali due to injury ... and his replacement was announced on SmackDown. 

The show kicked off with the announcement that a member of New Day, who was later revealed to be Kofi Kingston, would replace Mustafa in the Chamber.

Fightful.com first broke the news that Ali would be out of the match on Sunday and it was later reported he had suffered a concussion. 

"Unfortunately, some injuries I picked up over the last few months caught up to me," Mustafa captioned a video on social media about his situation. "WWE will not medically clear me to compete in this Sunday's #EliminationChamber Match. My apologies to anyone I let down."

Think Kofi is a good replacement? Sound off in the comments below.
