Geelong defender Lachie Henderson remains in doubt for the clubs season opener against Melbourne on March 25 after details emerged surrounding the extent of his off-season knee surgery. 

The former Blue has yet to begin running since undergoing a second arthroscopy which raises serious question marks over his availability for round one. 

“Lachie Henderson has not run since December 13, when he had another arthroscopy on left knee,” Sam McClure said on SEN’s Time On.

“He has not been training for two months…and unless something miraculous happens he’s not going to be playing round one.”

Geelong’s backline remains somewhat thin after the retirements of Andrew Mackie and Tom Lonergan and while Harry Taylor will move back to the defensive end in 2018, Henderson has been a key pillar of Geelong’s defence since his arrival in 2016.
