Both top seeds in the NFL play-offs booked their places in the Conference Championships as the Kansas City Chiefs beat the Jacksonville Jaguars and the Philadelphia Eagles dominated the New York Giants.

Chiefs quarterback Patrick Mahomes battled through an ankle injury to beat the Jags 27-20 and earn a fifth straight AFC Championship appearance.

The Eagles will host the NFC title game after they dominated divisional rivals New York from start to finish in a 38-7 success.

As the Chiefs continue to establish themselves as the next big winning dynasty in the league, they became just the third team to reach five straight championship games but will be left sweating on Mahomes' ankle in the build-up.

Mahomes limped out in the first quarter but returned to battle through the second half despite obvious discomfort as he threw two touchdowns to see off a stubborn Jaguars side.

A late Trevor Lawrence interception ended Jacksonville's chances as the Chiefs set up a game against either the Cincinnati Bengals or Buffalo Bills.
