MELBOURNE forward Jeff Garlett has failed to get through training at Gosch's Paddock on Friday morning and is in doubt for Sunday's game against Collingwood at the MCG.

The Demons will give the small forward until game day to prove his fitness but based on the training he completed he appears unlikely to be there against the Pies.

Garlett was put through a fitness test at the start of training, keen to push his way back into the side after he missed last Sunday's match against North Melbourne with an ankle injury.

The speedster attempted to do some change of direction running and that seemed to be the major issue in his restricted mobility.

Garlett even had the strapping on his ankle strengthened at one stage but it was obvious he was still limited.

After half an hour it was clear he was not right and he left the track after a long conversation with the club's medical staff.

Garlett rolled his left ankle at training last week and the high ankle sprain was the reason he missed the match against the Roos.

Should he be ruled out, Garlett will join key Demons Bernie Vince (suspension) and Aaron vandenBerg (ankle) on the sidelines.

Melbourne youngster Jayden Hunt will make his debut against the Pies, after making significant progress over pre-season.

Hunt, pick No.57 in the 2013 NAB AFL Draft, is one of the fastest players on the Demons' list and is a competitor across half-back.

Cameron Pedersen, Angus Brayshaw and Alex Neal-Bullen have all been named in Melbourne's extended squad.

Final teams are due to be announced later on Friday evening.
