Sam Lalor will miss the rest of the 2025 season and could require surgery on his latest hamstring injury.
Lalor lasted less than three minutes in the Tigers' clash against Geelong when he sustained an injury to his left hamstring while executing a tackle on the outer wing.
"After a strong, meticulous rehab, unfortunately, he did re-injure his hamstring. It is his third time on that hamstring and the second (occasion) with us," Richmond high performance boss Ben Serpell said.
"We are a bit concerned about the integrity of the hamstring structure.
"As part of that we will consult a few surgeons over the next little while to see if there is some surgical intervention available for us."
