Kansas City, Missouri - Patrick Mahomes' injured ankle is "definitely better" than before the AFC Championship Game as the quarterback prepares for his third Super Bowl appearance on Sunday.

Mahomes helped the Chiefs reach a third Super Bowl in five seasons by helping Kansas City defeat the Cincinnati Bengals in the Conference Championship on January 29.

It was a case of the NFL MVP frontrunner overcoming the odds, knocking off a Bengals team that had stunned them at the same stage last season, despite playing on a sprained ankle he suffered in the Divisional round win over the Jacksonville Jaguars.

Mahomes will now go against a vaunted Philadelphia Eagles defense in a mouth-watering Super Bowl LVII clash at State Farm Stadium in Arizona.

And he goes into the game seemingly in much improved shape.

Asked about his ankle at Super Bowl Opening Night in Phoenix on Monday, Mahomes replied: "It's definitely better, for sure."

"You never know until you get into the game, but it's definitely better than it was this time last week before the game."

"I'll play through all the injuries that the trainers let me play through."

He then joked: "[Tight end] Travis Kelce hurts my feelings like every single day and I still play so I'm still going to play through it and try to get a win."

Mahomes threw for 5,250 yards and 41 touchdowns in the regular season, marking the second time in his already glittering career he has surpassed 5,000 yards and 40 touchdowns in the same season.

The Eagles represent arguably his biggest test yet, though, their defense the best in the NFL by yards per play allowed. In two playoff games, Philadelphia's defense has given up a combined 14 points.
