Veteran Brisbane midfielder Mitch Robinson will miss the next 10 weeks of football after suffering a foot fracture against Sydney on Sunday.
Scans on Monday revealed the extent of Robinson's injury, with the 27-year-old now set to wear a moonboot and crutches for at least the next month.
"It's frustrating for Mitch who has had a strong start to the year," Lions' General Manager of Football David Noble told the club's website.
"Mitch is someone who leads by example and shows complete commitment week in and week out - we know that he will show the same commitment to his rehab.
"While he is recovering, Mitch will remain very much involved at the Club, mentoring some of our younger players as well as having involvement in the NEAFL program."
In addition to the Robinson news, defender Daniel McStay will have surgery during the week to repair a fractured hand, and will miss the next 2-3 weeks as he recovers from the injury.
