RETURNING Collingwood defender Tyson Goldsack has emerged unscathed from his first match at any level since rupturing the anterior cruciate ligament in his left knee in March.

Meanwhile, star midfielder Adam Treloar continued his recovery from left hamstring tendon surgery with another impressive training session on Saturday.

Playing about 65 per cent of game time in the Magpies' 63-point VFL victory over Sandringham at Victoria Park, Goldsack looked rusty on occasion but played well.

Goldsack was ready to return a month ago, an astonishingly quick recovery considering he had a traditional reconstruction, which usually requires a 12-month rehab period.

However, a disc concern in the 31-year-old's back meant he was forced to bide his time.

Coach Jared Rivers said Goldsack had no concerns post-match.

"He came off the ground really well and covered the ground well, so his fitness isn't really an issue. It's just probably getting (used to) that contact back playing footy again," Rivers said.

His comeback is particularly timely considering the raft of injuries the Magpies have suffered down back, with Darcy Moore (hamstring), Lynden Dunn (knee) and Matthew Scharenberg (knee) among those missing.

"It's just great to see him back. He's a credit to himself with how hard he's worked to get himself right, especially this late in the year, and he's fitted back in really well," Rivers said.

"It's always a bit nervous at times watching after a serious knee injury but he came back and played really well."

With the VFL finals starting next week, Goldsack is likely to line up in another game, while the AFL has its pre-finals bye.

Treloar won't line up in that match but is making progress.

"It's a real cautious approach – not many blokes do two hamstrings in the one instance, but he's been training really well," Rivers said.

"He had a really good session this morning and pulled up really well."
