Ferguson, 23, has signed a professional tryout contract.
The 2017 seventh-round pick hasn't played many games in recent years, but still has some interesting stats.
In 13 games last season with the Golden Knights' academy club, Ferguson maintained a 2.90 goals-against average and a .907 save percentage.
He played one game in the NHL, in 2017-2018 with the Golden Knights.
