SAM WEIDEMAN will make a childhood dream come true when he makes his debut with Melbourne against Hawthorn on Saturday at the MCG.

He will become the third generation of the Weideman family to play VFL/AFL football when he takes the field against the Hawks.

The 19-year-old told AFL.com.au he was "stoked" when coach Paul Roos gave him the news.

"It was a really amazing feeling," Weideman said.

"I'm so excited to get to Saturday and hopefully the boys can get a win."

Teammate Christian Petracca – who made his debut in round six – gave Weideman a hug as news spread that he was to become the fifth Demon to debut in 2016.

"All the boys got around me and it was really special," Weideman said.

I'm still shaking a little bit now."

The 195cm forward likes to launch for his marks but has been told to soak the moment in and stay calm and composed.

He conceded he would need to add some bulk to his lean frame in the next few seasons.

"The weights coach is putting a lot of work into me," Weideman said.

"I still have a pretty skinny frame at the moment unfortunately and I will put in the hard yards, especially over the next few pre-seasons and hopefully fill into my body and see where it takes me."

His bloodlines are impeccable with grandfather Murray Weideman a member of the Australian Football Hall of Fame, having played in two premierships and won three best and fairests in his 180-game career with Collingwood.

His performance in the 1958 Grand Final when he led the Magpies to an upset victory over Melbourne – which was shooting for its fourth successive flag – assured him a place in football history.

Sam's father Mark played 28 games and kicked 34 goals for Collingwood between 1981-1984 before playing VFL football.

The Weideman family joins names such as the Kennedys, Murphys, Hirds, Silvagnis, Cordners, Edwards, Reids, Howells, Grimleys and Grahams with three generations having played VFL/AFL football.
