Richmond ruckman Ivan Maric will miss six to eight weeks after having bone spurs removed from his injured ankle on Monday.
"It's good to get that done now and start moving into his rehab phase and hopefully get him back on track soon," Richmond's elite performance manager, Peter Burge, said.
"He's been able to train with it in the past couple of weeks but he hasn't been 100 per cent comfortable.
"It was a decision we had to make - does he play with it the whole year or do we just get it done now and get him right? That's the decision we made with Ivan and we're happy with that."
Youngster Ben Lennon will be sidelined for three to four weeks after what the club described as minor knee surgery on Monday.
Meanwhile, Geelong expects ruck-forward Nathan Vardy to rebound strongly from the knee reconstruction that continues his rotten injury luck in the AFL.
Vardy hurt his right knee in a training drill on Saturday and football manager Neil Balme said on Monday a traditional reconstruction was the most likely outcome.
It would mean the 22-year-old misses the entire season - a massive blow for Vardy and the Cats.
But Balme said Vardy's run of injuries, particularly the hip problem that restricted him to only two games in 2012, would help the key position player cope with this latest setback.
''I think going through the hip thing has probably made him much more resilient,'' Balme said.
''It's changed the way he is around this place. He was just a young colt when he came in and I think that's helped him understand how important the game is to him.''
Balme said Vardy was coping well with the bad news but admitted it was a blow to his teammates.
''I've spoken to him a couple of times and he's actually very good,'' Balme said.
''He'll be fine, I've got no doubt.
''Everyone's pretty upset by it but good organisations move on.
''Nathan's got a big part to play in that as well, how positive he is around the place.''
Vardy is the latest pre-season injury blow for Geelong, with Steven Motlop recovering from knee surgery, and a back operation likely to sideline Allen Christensen until round 10.
While Vardy also had injury troubles last year, he returned in round 18 and impressed for the rest of the season.
Melbourne midfielder Luke Tapscott, who hurt a knee in the Demons' intraclub match last Thursday, is expected to be sidelined for two weeks.
