Patrick Mahomes is telling his team 'we can come back, we've done it so many times, don't let us down'. But San Francisco are saying 'we're going to continue to get after this quarterback'.

The 49ers' defence is bringing it again. DeForest Buckner brushes off two men in the Chiefs' defensive line to sack Mahomes for a nine-yard loss.

Another nervous moment for Chiefs fans. Kwon Alexander gets his hands to a Patrick Mahomes pass but he can't hang on for the interception.

Mahomes finds Tyreek Hill on the next play for a first down. They're into 49ers territory.

After watching that fightback against the Titans, there's no chance we're going to do that Sam.

As he said to his team-mates when 24-0 down, "let's take it one play at a time".

Travis Kelce takes a direct snap and scrambles for a first down. The Chiefs are six yards short of halfway at the end of the third quarter.

This is the one-yard touchdown from Raheem Mostert which gives the 49ers a 10-point advantage.

Patrick Mahomes faltered on that last drive. Now we're going to see what the young man is made of.

The Chiefs quarterback scrambles for a first down. Just over a minute left in the third quarter.

James Croyden: Raheeeeeeemmm!!

Matty Evans: I thought @JimmyG_10 couldn’t pass?? Everyone should apologise now.

The 49ers offence showed UP on that drive didn't they?

For the first time tonight, a side leads by more than one score.

The Chiefs came back from 24 and 10 points down in the play-offs, but have the 49ers defence now got the measure of him?

The Chiefs are playing against a fierce pass rush and the 49ers offense will continue to run the ball down your throat and use up that clock so this is the worst position for the Chiefs to be in right now.

Jimmy G has really impressed since that early interception. He's now completed 17 of 20 passes for 183 yards and he's put his side in a good position.

Still only 10 in it though. But he's giving the Niners a balanced attack.

That interception sure was a game-changing play by Fred Warner. The 49ers have just picked up seven points on the back of it.

Jimmy Garoppolo found Deebo Samuel for 16 yards, then Kendrick Bourne for 26.

Kyle Juszczyk makes a 10-yard catch to get the 49ers within a yard and Raheem Mostert punches it in for the TD.

That is the first interception Patrick Mahomes has thrown in the post-season. You can blame me Pat (see 1:34).

Joe Smith: Isn't this supposed to be Mahomes big game? So far he hasn't really shown up and that interception has only made things worse for the Chiefs.

Adam Stubbings: Niners D showing up big time on that drive. Bosa is a monster. First time tonight that the Chiefs look on the back foot.

Jack: WOW! Mahomes what was that??

Could that Mahomes interception be a defining moment in Super Bowl 54?

That was a huge minute or so from Mahomes - and not in the way we expected. A fumble and then a pick! Have the Niners rattled him?

That is a game-changing play.

Patrick Mahomes may have got away with it there but the pressure pays off on the next play.

The Chiefs' quarterback targets Tyreek Hill but it's intercepted by Fred Warner.

Oh, big let-off there for Patrick Mahomes.

Nick Bosa gets to the quarterback to knock it out of his hands, but Mahomes recovers it to maintain possession. Still a nine-yard loss though.
