Former Melbourne high-flyer Shaun Smith says his his son Joel will fill the void down back left by emerging defender Jake Lever, who last week ruptured his ACL.

22-year old Joel Smith will get his chance to cement a place in the Demons' back six when his side takes on Collingwood in their blockbuster Queen's Birthday clash on Monday.

And there are big shoes to fill, as Lever was recently back to his brilliant best, which coincided with Melbourne's hot streak of form.

โ€œIโ€™m rapt for him. Iโ€™m actually quite nervous, because itโ€™s obviously a huge game,โ€ Smith snr toldย The Age.

โ€œHeโ€™s put a lot of hard work in, heโ€™s obviously had a breakout year last year playing his first game, then he also had two really bad injuries [shoulder and knee].

โ€œHeโ€™s been knocking on the door for the last month. Because Melbourne are going so well, heโ€™s just hung tough. I think itโ€™s been good for him to play all that footy down at Casey, just to get his confidence up.

โ€œI think heโ€™ll be OK. He proved last year he can handle that level. Obviously it goes up another notch. I suppose itโ€™s the closest thing to a grand final.โ€

Smith snr played 109 games for North Melbourne and Melbourne between 1987 and 1998, and took a grab dubbed by many as 'Mark of the Century' in Round 22, 1995.

Meanwhile, Joel only managed three games from his debut season in 2017 after being heckled with injuries.

โ€œObviously Jake Lever, you donโ€™t want to see anyone get injured but obviously him going out of the team [has opened up] Joelโ€™s spot,โ€ Shaun said.

โ€œJake Lever gives you a bit of run off the back line, and I suppose Joelโ€™s a runner as well.

โ€œHeโ€™s been playing some really good footy at Casey. Just playing his role well, and done some lock-downย jobs as well. Heโ€™s ready to go.โ€
