Melbourne Storm halfback Ryley Jacks celebrates a try.

'Thumb wars' not hampering Storm

Dale Finucane and Tim Glasby are good mates, but this is taking the Mickey.

The Storm duo – who room together on away trips – are both nursing thumb injuries. Finucane is expected to play this round while Glasby will spend some time on the sidelines.

Halfback Ryley Jacks doesn't think there's a digit-related curse at the club just yet.

"It's just one of those flukey things that happens," Jacks said.

"Those two are pretty close so it's pretty funny that they've both done thumbs. We might have to strap ourselves, yeah."

Throw in a knee injury to leading prop Jesse Bromwich, and there could have been concerns.

But Joe Stimson, Nelson Asofa-Solomona, Sam Kasiano and Glasby have all stepped up admirably, with Melbourne playing their best football of the season over the last three weeks.

The Storm plays St George Illawarra on Sunday and are aiming for four straight wins.

And Jacks thinks his forwards should take a heap of credit for their recent success.

"They've been unreal, with a 'next man up' mentality," he said.

"They're the best in the competition for sure. You lose someone like Dale, and you bring someone in like Joey Stimson, who is a definitely a first-grader.

"You've got great depth in the forwards and now that Timmy's out with his thumb, hopefully Dale can come in and take his spot, but we'll see."

Jacks is quietly building into some form of his own after three straight games in the first-grade side.

"I've felt more comfortable and more confident in the games we've played," he said.

"Playing Queensland Cup at the start of the season probably doesn't prepare you for the NRL. The pace is next level. It took me a while to get back into the rhythm of first-grade footy.

"[It's about] just knowing where to be, play after play, because it happens so quick, and that's the difference between the reserves and first grade."

The Storm aren't getting carried away after scoring 50 points against the Warriors.

In typical Craig Bellamy fashion, it will be about getting back to the fundamentals.

"You just go back to the start and worry about basics," Jacks said.

"Putting 50 points on is awesome, and you can get carried away with that, so no doubt today when we sit down with the coaches, we'll just be drilling in the simple things, and not getting ahead of ourselves."
