Scans have revealed a strain that will sideline Windhager for at least a month and could cost him most of the closing stages of 2024. 

Ross Lyon has handed Windhager some key tagging roles across the past couple of months, clamping Harley Reid in a half, then Touk Miller, before getting jobs on Lachie Neale and Zak Butters.

St Kilda lost key forward Max King for the remainder of the season last week when the former pick No.4 suffered a posterior cruciate ligament injury against Port Adelaide. 

Anthony Caminiti is also set to miss at least another three weeks with a high ankle sprain.

Riley Bonner and Paddy Dow will need to prove their fitness later in the week to be cleared to make the trip to South Australia to face Adelaide on Saturday night.

After playing in an elimination final last year, St Kilda has won six games across the first 17 rounds to sit in 14th spot on the ladder.
