Jan. 22 (UPI) -- John Cena is suffering from a left ankle injury, WWE has announced, making the 16-time World Champion questionable for Sunday's Royal Rumble pay-per-view event.
Cena was injured during the main event of last week's Monday Night Raw where he faced off against Finn Balor, Drew McIntyre and Baron Corbin in a Fatal 4-Way match to determine the No. 1 contender for Brock Lesnar's Universal Championship. Balor won the bout.
The injury seemingly occurred when McIntyre put Cena into the Ankle Lock submission hold, WWE said. The injury was then exacerbated on Monday while Cena was training his legs at the gym.
Cena previously announced that he would be competing in the Men's Royal Rumble Match on Sunday, featuring 30 superstars from Raw and Smackdown. The winner of the annual Royal Rumble match is given a championship opportunity at WrestleMania.
He can be seen in Transformers spinoff Bumblebee, opposite Hailee Steinfeld.
