Star Magpie Adam Treloar has suffered a minor injury setback, the club confirmed.
The midfielder experienced calf tightness during the Magpies' return to training on Monday, with scans confirming a minor strain.
The 27-year old will now ease his way back into the full training program after leaving the track early in Monday's session.
Treloar is expected to be ready for Round 2 in 24 days time.
Collingwood GM of Football Geoff Walsh confirmed the injury news to collingwoodfc.com.au.
“Adam was feeling tight and came from the track as a precaution. A scan has confirmed a minor strain that will see Adam’s training loads wound back for a week or two,” Walsh said.
Treloar missed Round 1 with a hamstring strain.
