Pearce denied the hard Optus Stadium turf had anything to do with his latest setback, although he was reluctant to go into details about why it may have occurred.
“I’ve obviously had plenty of tests done with my other leg, doing it twice, and I’ve never had anything come back on my bone density,” Pearce said from St John of God hospital on Friday.
“My running mechanics are always pretty good. The docs and physios are looking at the game and a few different incidents.
“I don’t really want to get into how it happened and what happened on the day. I might just leave that for a bit later.”
Pearce had surgery this week to insert screws and a plate into his left ankle.
The 23-year-old will return to hospital to have a cast put on his leg, and he will also be in a moon boot.
Pearce had been in career-best form this season, and is confident he will come back from his latest injury as a better player.
“I have been in this situation before so I know what it feels (like),” said Pearce, who spent 672 days on the sidelines following his two leg fractures.
“This injury certainly isn’t as bad as my last one. It’s not anything too drastic. Once the bone heals, I’ll be fine.
“I missed almost 20 months of footy with the last injury, and was able to come back and be a better player on my return, so that’s going to be my focus on this recovery as well.
“Hopefully I’ll have a full pre-season, get to work and come back a better player than what we’ve seen this year.”
Pearce backed Griffin Logue to fill his spot for the rest of the season, starting with next week’s home clash with Port Adelaide.
