Brisbane midfielder Mitch Robinson will miss the remainder of the season due to a broken foot.
Robinson played the opening seven games of the season, averaging 20 disposals, before injuring his foot in round seven against Sydney.
It was initially expected he would miss around 10 weeks, however, it has since been revealed he has ligament damage that has required surgery to heal.
He has spent the past month in a moon boot, which has improved the injury and continued improvement could see him return for the final few weeks of the season, but Fagan said the logical choice was to send him in for surgery now rather the end of the year.
“Robinson is gone for the season, he is done,’’ he said.
“The bone is healing, but where the bone and ligament is attached there is damage so he has to have that repaired.’’
The Lions had the bye this week, before hosting the Dockers at the Gabba in Round 12.
