Liam Henry will miss a minimum of six weeks after scans today revealed a high-grade left hamstring strain.

Henry, who was one of St Kilda’s best players in last night’s win over Collingwood, sat out final minutes of the game with suspected severe cramp, however further assessment revealed a more significant setback.

The latest update follows on from Mason Wood’s concussion and collarbone injury from the opening minutes of Thursday’s match, which will sideline him for a similar period.

“This is obviously a terrible blow for Liam, who has impressed in his first two games at the club,” EGM Football David Misson said.

“Liam’s setback is far greater than we initially thought, especially given he has never had an injury of this type before.

“At this stage, Liam’s return-to-play timeline sits at approximately six to eight weeks.

“The shorter turnaround between games early in the season has presented its challenges, however we have full confidence that Liam will attack his rehab with the same intensity he does on game day to make himself available as soon as possible.”

St Kilda’s full injury report will be published on saints.com.au on Tuesday.
