Richmond midfielder Nathan Drummond has ruptured his anterior cruciate ligament for the second time in two years and will require surgery to repair the injury, which will see the youngster miss another 12 months of football.

Drummond ruptured the ACL in his left knee during Richmond's VFL match on Saturday, which is almost two years to the weekend in which he injured the ACL in his right knee in his debut against Melbourne on ANZAC Day eve in 2015.

Tigers coach Damien Hardwick said the club has faith in the 22-year-old to bounce back from the injury.

"It's really disappointing for the lad," Hardwick said.

"We've got complete faith in the kid that he'll get back on and get to it, the way he did his rehab last time.

"We think he's going to be a quality player (and) we were really pleased with his progression.

"It's a long way back from a knee 'reco', but we're very confident with the type of kid he is that he'll get back and play some good footy for us at some stage."

Drummond returned to senior football late in 2016, playing four matches at AFL level after returning to the VFL in the middle of the season.
