Alan Didak's recovery from a hamstring injury is progressing nicely according to Collingwood's Director of Football Geoff Walsh.

The 30-year-old, who has battled a variety of injuries during the past two years, did not appear in any of Collingwood's four NAB Cup games but is now in a position where a return to the game is not far away.

"Alan is getting towards the sharp end of his recovery," Walsh told collingwoodfc.com.au.

"He is stepping up his training and has had no setbacks. He's on target for a return in three weeks' time."

Didak is one of four key senior players who are still making their way back from injury.

Defender Ben Reid, who injured his knee during last week's NAB Cup win over West Coast, is rated a 1-2 week proposition while Luke Ball (knee) and Dale Thomas (ankle) are both anticipated to return in 3-4 weeks time.
