THE WESTERN Bulldogs have locked in one of their most promising players for the long-term, with ruckman Tim English signing a contract extension.

The 21-year-old was signed until the end of 2020 but has added a further two years to his deal, tying him to the club until the end of 2022. 

The West Australian had reportedly attracted interest from Fremantle, but will continue to lead the Dogs' ruck division.

It has been an interesting year for English, who has played 12 games for the season, taking his career tally to 21. 

He has shown flashes of his talent, but has also faced challenges against some of the premier big men in the competition as he continues to build his frame. 

"Tim is one of the most exciting young ruckmen in the competition and we are thrilled to have him recommit to our club," Dogs list manager Sam Power said.

"Watching his development as a player over the past three years has been really pleasing.

"Naturally, ruckmen take time to develop, but Tim has taken some big steps this year at AFL level."

English was drafted with pick 19 in the 2016 NAB AFL Draft.
