BRISBANE Lions midfielder Dayne Beams may miss the rest of the season to nurse his left knee injury, Lions chief executive Greg Swann says.

The 26-year-old received a knock to his troublesome knee during the Lions' 78-point loss to Collingwood on Saturday night.

After starting the second half up forward, Beams was forced to sit out of the match midway through that term after experiencing the same knee tendinitis symptoms he has battled for most of the year.

Swann said Beams' knee "blew up" after his latest knock, adding the Lions would not rush the gifted midfielder back into the squad.

"We'll see what happens with it but if it's not right it might be a similar thing to Nat Fyfe where you just put him out and make sure we get him right," Swann told radio station 3AW on Sunday.

"If it takes 10 weeks or the rest of the season, so be it."

Beams has had a luckless run with left knee tendinitis since early in the new year, and only took part in his first appearance for the season against Port Adelaide last Sunday.

He will now have scans to determine the severity of his latest setback before a decision is made on his recovery.

Last-placed Fremantle last week ruled Nat Fyfe out for the remainder of the year to nurse his fractured left fibula, as the club turns its attention to 2017.
