MELBOURNE recruit Adam Tomlinson and small forward Charlie Spargo have both missed the official start to the club's pre-season, with the latter in a moonboot after rolling his ankle.

Neither participated in the club's time trial on Monday, but Melbourne is hopeful both will return to training shortly.

"Adam unfortunately strained his calf last week while away from the club," Melbourne's football manager Josh Mahoney told Melbourne Media.

"He was completing a running session when he felt some tightness, with scans revealing a calf strain. He will be running next week."

Although the 26-year-old couldn't join in with the main group at Gosch's Paddock, he was still in attendance despite being entitled to a longer break following his Grand Final appearance for the Giants.

Spargo, who has played 26 games across his first two seasons in the red and blue, was also watching on from afar after injuring his ankle. 

"Charlie landed awkwardly and rolled his ankle while participating in a skills session last Friday," Mahoney said.

"Charlie has been wearing a moonboot and crutches as a precaution. We expect him back running next week before progressing back into the main group prior to Christmas."
