Whitfield was sanctioned by the AFL for six months for breaching rules regarding conduct unbecoming, when he reportedly hid at the house of former Giants staff member Craig Lambert, with the help of Graeme Allan who also worked at the Giants last season.
The GWS staffers were banned for a year due to the incident, but with Whitfield’s reduced sentence, he was able to return to the club on Tuesday under the terms of the penalty.
“In terms of his training, he’s prepared himself really well off his own bat in the last three or four months away from the footy club,” coach Leon Cameron told Fox Footy.
“It was great that he turned up in high spirits and the players loved having him around.
“He understands that a mistake was made and we’re looking forward to the future for Lachie.
“We feel as though it’s onwards and upwards for him and we can’t wait to get him back into our AFL team come that mid-year mark.”
Whitfield must wait until at least round eight before he’s available for selection once again.
