Full flight... Canberra-bound fullback James Tedesco is one of many Tigers set to return from injury on Sunday.

Healthiest Tigers squad in two years

Not once in his 18 months at the helm has head coach Mick Potter ever had a selection headache this big. 

For the first time in almost two years the Wests Tigers are just about at full strength, with injured utility Tim Moltzen the only player not considered by Potter for this weekend's clash with Newcastle.

Forwards Cory Paterson (finger) and James Gavet (hamstring) are both understood to be ready after recovering from injuries, but have been given one more week off as a precaution. 

Fullback James Tedesco (ankle) and second-rowers Curtis Sironen (foot) and Liam Fulton (back) return for Sunday's game, while utility Dene Halatau (ankle) will finally start his second stint as a Tiger through the NSW Cup. 

The club's suddenly empty rehab group has prompted franchise prop Aaron Woods to dream of what a healthy squad can accomplish. 

"It's about time, there's always been about 10 or 12 in there. To only see about 3-4 in there today, we're really happy," Woods said. 

"We've usually had half a compliment of players in the team so it's been frustrating. But as you've seen at the start of the year, we were playing some good footy because we had a full strength squad. 

"You get a few injuries, it tests your depth. But we've also got Curtis [Sironen] back too... to have him back on the edge will be a massive addition to the club. Only thing we can do is look forward." 

The inclusion of Tedesco is a huge boost for a side that has lost three of its past four games and is one of seven teams jammed in the middle of the table on 14 points. 

Woods said that while many of his teammates were still coming to terms with Tedesco's decision to move to Canberra at the end of the season, he felt the young fullback had made the correct call. 

"Teddy was enormous at the start of the year. We probably weren't happy with his decision last week about staying at our club, but as a mate, he's got the right decision. It's a massive boost to us to have him back this week," he said. 

"We're on 14 points, there's about six other teams on 14 points, there's [two] teams on 16, and [two] teams on 12. So it's a massive game. It's a must-win game for us.

"It's ridiculous. It's a win or loss in between everywhere. If you're off for that one game, [there are] that many teams that can jump you."

Fellow prop Martin Taupau said Newcastle's back three, as well as their centre pairing Joseph Leilua and Dane Gagai, would be their biggest threat on Sunday. 

"They're all very quick, very strong. And then there's big Willie Mason. He's a very big player, very strong. So we've got a lot of players that will step up to the challenge. It'll be exciting," he said.
