Josh Allen praised Buffalo's defense after the Bills clinched a place in the AFC Championship Game - then revealed how he played a part in Taron Johnson's record-tying touchdown.

Johnson 101 yard return

The Bills overcame the Baltimore Ravens 17-3 on Saturday to progress in the NFL playoffs, quarterback Allen throwing a touchdown pass to Stefon Diggs in what was a hard-fought victory.

That score put Buffalo 10-3 ahead in the third quarter, though the Ravens threatened to respond with a drive of their own that put them in range to score.

However, cornerback Johnson picked off a pass from quarterback Lamar Jackson in the end zone and then returned the ball 101 yards, creating clear daylight between the teams in a low-scoring contest.

Buffalo will be involved in the AFC Championship Game for the first time since 1994; they will either travel to the Kansas City Chiefs or host the Cleveland Browns next Sunday.

"This was a fun one to be part of. There are some things we can clean up but, at the end of the day, it's the playoffs: you win or go home," Allen told the media.

"Our defense stepped up. Taron Johnson made the play that just changed the game. Unbelievable.

"We've got to turn our focus to the Browns or Chiefs next week - and that's what we were going to do."

Johnson tied the NFL record for the longest interception return for a touchdown in a playoff game, matching Green Bay's George Teague, who achieved the feat for the Packers in the 1993 Wild Card round against the Detroit Lions.

Allen divulged how he played a minor role in helping his team-mate produce a play that will live long in the memory.

"I saw him come out of the end zone with a lot of bodies around him, and usually you want them to stay in. I thought he was going to get tackled at the five or the 10," he said.

"I tell you what, for Tre'Davious White to go ahead and get a block on Lamar, spring him free, was unbelievable. You practice for those situations.

"I'm going to give myself a pat on the back, as in practice I go up behind him and try to punch the ball out. So Taron had that extra sense to look back, feel that someone was coming and to hold onto the ball.

"It was an unbelievable play, one of those that will be remembered for a really long time."
