Kuwarna forward midfielder Izak Rankine is expected to miss about three weeks after injuring his hamstring in the final quarter of the Round 10 match against Collingwood at the MCG on Saturday afternoon.

Assistant Coach Nathan van Berlo confirmed the news on Monday morning after speaking with High Performance Manager Darren Burgess.

Van Berlo said it was disappointing, following the 24-year-old's solid performance against Collingwood, which included 30 disposals, 16 contested possessions, eight clearances and 699 metres gained.

"Speaking to Darren (Burgess) we believe it's similar in nature to what he did last year and it will be around about the three-week mark," van Berlo said.

"He's (Rankine) been playing some outstanding footy and (it was) arguably the best game I've seen him play on the weekend, just his ability to win the footy, hit the scoreboard and he's been doing that for weeks on end now for us, so it's going to be a big loss for us in the interim. 

"But I guess all we can do is hope that he comes back fresh and ready to go and attack the remainder of the year for us."

Rankine suffered the injury with 16 seconds left in the final quarter of the match, in which Kuwarna went down by four points.

Van Berlo said it was another "frustrating and disappointing result".

"We did more than enough to get the result that we should've got and upon refection there were a lot of things we could've done better to start the game and ultimately finish the game to get the result we wanted and the win we felt we deserved.

"I know we've had enough of these hard learnings and we want to make sure we fix those moving forward."

Kuwarna plays Waalitj Marawar (West Coast) at Adelaide Oval on Sunday at 4.10pm.
