Melbourne is set to unleash Pick 13 from last year's draft Koltyn Tholstrup as the latest debutant when they take on Brisbane at the MCG.

Tholstrup - who hails from Esperance in Western Australia - came into the Demons as an AFL-ready midfielder, with his size and strength key features of his game.

Standing at 186cms tall, the 18-year-old has played as a mid-sized forward and pinch hit through the midfield at times, likened to North Melbourne's Cam Zurhaar and Brisbane's Cam Rayney.

Tholstrup has had plenty of senior football experience playing for Subiaco in the WAFL. At 186cms and 86kgs with a strong mark and penetrating kick, Tholstrup averaged 18.3 disposals, six marks, six inside 50s and just under two tackles per match for Western Australia in the National Carnival.

The Western Australian will be the third debutant for the Demons, joining Caleb Windsor and Blake Howes in donning the red and blue.

Jack Billings is another who crossed from St Kilda to Melbourne to feature as a new face under Simon Goodwin.

Tholstrup is likely to replace the suspended Kysaiah Pickett, who's one-game ban was upheld at the Tribunal on Tuesday.
