Richmond livewire Jack Higgins is locked in as Tiger until at least the end of 2021, after signing a contract extension this week.

Higgins, 19, has played 11 games in his first season since making his AFL debut in round three against Hawthorn.

His new deal has been in the works for some time, with Higgins following the trend of draftees extending their base two-year contract in their first season.

The exciting midfielder/forward is already a fan favourite for his exuberant personality, goal celebrations and contagious energy.

And, the players are also entrenched in the Higgins camp, with his famous half-time rev-ups having them in hysterics before they've broken from their huddle for the start of the third quarter.

While his speeches, according to teammate Shane Edwards, aren't consistently concise, they've become significant for the Tigers in recent weeks.

"He just gives us an extra rev-up," Edwards told AFL.com.au after their round 15 win over Sydney.

"He's done it the last few weeks. Nothing relaxes the boys and gets them up more than a 'Higgo' speech. There's a lot of mumbles and a lot of stumbles, but we love it."

They now have the opportunity to enjoy Higgins' sermons for at least another three seasons, with the No.17 draft pick joining the likes of Cam Rayner, Andrew Brayshaw, Paddy Dow, Luke Davies-Uniacke and Jaidyn Stephenson to ink extensions in their debut years.

Richmond football manager Neil Balme said Higgins had already made a big impact in the short time he'd been at Punt Road.

"Jack has made an exciting start to his football career and is settling into the club very well for a young man," Balme said.

"We're looking forward to him continuing his development both on and off the field, he's a great talent and addition to our club."
