With two games left for the season, and Richmond not in finals contention, Brennan will most likely not play again in 2020, according to a source close to the player.
Brennan has not been able to do fitness work, including running, since the incident, reflecting Richmond’s ultra-cautious attitude to their captain’s injury.
Richmond has been contacted for comment.
Meanwhile, Melbourne’s Sarah Lampard was sent for scans on Monday to determine whether she had ruptured her ACL.
Lampard collided with Carlton’s Darcy Vescio in the third quarter and clutched her left knee once hitting the turf.
She was stretchered off and the game stopped. Melbourne said it would provide an update on Lampard’s condition once the scans were complete.
The 22-year-old ruptured the ACL in her right knee two years ago.
If an ACL injury is confirmed, Lampard would join Maddy Guerin, Ainslie Kemp, Shae Sloane and Katherine Smith as Demons nursing one. It would also be the 15th torn ACL across the AFLW this season.
Geelong star Nina Morrison became the 14th of the season when she tore her ACL for the second time in the Cats’ loss to North Melbourne on Friday night.
