The extent of the knee ligament damage suffered by Logan Swann against Penrith on Friday night should become clearer today.

Swann yesterday saw a specialist and underwent a scan at the Yorkshire clinic and it is unlikely he'll be fit enough to play against Wigan on Friday night.

The rangy back rower capped a fine display against the Panthers with a debut try but ended up hobbling out of the game after wrenching his knee in a tackle by Preston Campbell.

Swann spent most of the weekend with his leg elevated and packed in ice in an attempt to restrict the severity of the injury.

"It feels like medial ligament damage," he said.

"I was trying to run over Preston Campbell. He was diving in at people's knees all night and he caught mine and it twisted awkwardly."

Swann said he'd suffered a similar injury, to his other knee, which had kept him out for four weeks, although he did not think his current injury was as serious.

Having endured losses in a World Cup and NRL Grand Finals, Swann rated Friday's victory as the best moment of his career.

"It's up there at the very top. I've had plenty of runner-up medals but that's the first time I've won anything as big as that, so it would have to be the highlight of my career.

"To keep a side like that to four points was amazing. They were the best attacking side in the NRL in 2003."

Playing in front of Bradford's fans for the first time in a big match had been an incredible experience, he said.

"It was fantastic. The fans are amazing. When the boys were defending their line they were all on their feet applauding. That's something I've not been used to, coming from Down Under.

"It makes the hairs on the back of your neck stand up."

Scoring on his debut had capped off the night but Swann was keen to give most of the credit for his try to man-of-the-match Mick Withers. "Mick did all the hard work," said Swann.
