Karl-Anthony Towns has agreed to a four-year, $224million 'supermax' contract extension with the Minnesota Timberwolves.

It is a move that ties Towns, 26, to the franchise until after the 2027 playoffs, as he still has two seasons remaining on his five-year, $158m deal he signed ahead of the 2019-20 season.

The Timberwolves centre – who called himself the greatest big-man shooter of all time after winning this past season's Three Point Contest during All-Star Weekend – is coming off his second career playoff appearance, and the first since 2018.

He averaged 24.6 points, along with 9.8 rebounds and 3.6 assists, shooting 41 per cent from three-point range on 4.9 attempts per game.

Partnered with the number one pick of the 2020 NBA Draft, Anthony Edwards, the Timberwolves believe they have the cornerstones of what could turn into the most successful era of Minnesota basketball since Kevin Garnett left for the Boston Celtics in 2007.
