ST KILDA key defender Rhys Stanley's leftknee injury may not be as serious as first thought, although the Saints andcoach Scott Watters will be sweating on the results of scans on Monday.

"It's a hyper-extended knee, which is potentially a good thing, andit doesn't look that serious," Watters said after his side defeated theSydney Swans by 23 points in their NAB Cup clash at Etihad Stadium on Sundayafternoon.

"But having said that, it's very hard to make these assessments, orhave some finality on these assessments, until you get a scan.

"It looked bad initially; it doesn't look quite as bad now."

The 22-year-old hyper-extended his left knee midway through the thirdquarter of the Saints' 0.13.12 (90) to 1.8.10 (67) come-from-behind triumph.

Stanley missed 10 games with hamstring injuries in 2012, and Wattersadmitted his heart sunk when he saw his promising big man limp off.

The other talking point out of the game was the fact the Sydney Swansbreached the trial interchange cap – on purpose.

While it was highlighted on the television coverage – the Swans made 23interchanges in the final quarter, instead of the allowed 20 – it was laterconfirmed to AFL.com.au that theSwans and the AFL match day manager were aware of the infringement.

Under the interchange rule, a club is permitted, in theory, to make amaximum of 23 interchanges for the quarter – under the provision that thoseplayers coming off the ground must sit off for a period of 15 minutes.

Asked post-match about the incident, Swans coach John Longmire was notacross the development.

"It's just something you've got to be mindful of. I wasn't aware ofany numbers or anything over, it is what it is," Longmire said.

The Saints trailed the Swans – who were much improved from their NAB Cupround one showing – at every change, but booted five goals to one in the finalterm to seal the victory.

Small forwards Ahmed Saad (two goals), Trent Dennis-Lane (two) and SamDunnell all proved to be a handful up forward, even in the absence of captainNick Riewoldt.

Saad and Dennis-Lane – coming up against his old team for the first time– both booted brilliant snap goals.

For the Swans, Mike Pyke played a lone handin the ruck (29 hit-outs), with Daniel Hannebery (30 disposals) and stand-inskipper Jude Bolton (27 and six tackles), typically leading the way.

Whatit means: Swans coach John Longmire said the club is inthe middle of a strong training block, but was pleased with a much improvedshowing. However, both coaches stressed their focus was firmly fixed on roundone. For the Saints, the development of their small forwards will be anotherthing they can take out of the game.

Whatthe coaches said: "I don't read too muchin to NAB Cup games. However, we had a number of kids out there today that wereexposed to some key roles. That sort of exposure you can't buy. To be behind,on a number of occasions, and to continue to dig themselves out of that, they(would've) gained a lot of confidence."- St Kilda coach Scott Watters

"We played in patches that were a bitlonger and sustained this week, whereas I don’t think we had any patches lastweek. I thought for the first 15 minutes of quarters we played some pretty goodfooty." – Sydney Swans coach JohnLongmire.

Fantasysnapshot: While Leigh Montagna, as he usually does, wasthe standout with 120 fantasy points, it was Arryn Siposs who seemed to make significantstrides against the Swans. He booted a brilliant goal from outside 50 to goalong with his 12 disposals and 45 fantasy points. Scott Watters said the aimis to educate the youngster in a number of roles, not just stationing himforward – which could be good news for his fantasy production.
