The Sharks haven't lost in 2015 yet, and they will have added incentive tomorrow for Graham's big match.

They will take on Wingham Tigers at Regional Stadium for sponsors day and the Men of League Foundation round which aims to raise money for the vital service. Jerseys will be auctioned, and a percentage of the proceeds, and gate takings, goes to the foundation, and to the family of young Shark Xavier Dunn.

Dunn is fighting a brain tumour.

A portion of the food takings from the burgers and schnitzels at Tacking Point Tavern after the game is even going to the cause.

It's a big day for players, supporters and sponsors, and Sharks' captain coach Matt Shipway was confident his team could turn up for the occasion.

Shipway said day belonged to Graham. "It's a good milestone for him," Shipway said.

"Hopefully we can play well."

Graham has been a standout for the team this season, and Shipway has been thrilled with his man up front.

"He does a lot of work which could go un-noticed," he said of Graham.

"He's got a quick play the ball and he's good in defence."

Graham couldn't wait to pull on the triple figure jersey, but he said it wouldn't get much wear after that.

"It'll go straight to the pool room," he said. He can't remember exactly which year he first played for the Sharks' higher grades, but Graham estimated it was about 2008.

"That's showing my age, isn't it?" he said.

Sharks president and former coach Phil Trembath rates Graham highly, but he hasn't always had that view.

Trembath initially thought Graham was solid, but didn't stand out.

"In the early stages, I thought he was there or thereabouts," Trembath said. He soon changed his view.

"He's one of these blokes who always wants to play first grade," he said.

Trembath called Graham into the Group 3 and then North Coast teams, where Graham has shone.

He's not the biggest prop getting around.

"He's got the build of a second rower, but he's tough enough to be a front rower," Trembath said.

Off the field, Graham is also a star. He's on the club committee and is as keen as he is in a Sharks playing jersey.

"He's a pretty good club stalwart," Trembath said.

The hosts won't be at full strength tomorrow.

Tom Maguire was under an injury cloud this week with a stomach problem.

Sharks captain coach Matt Shipway wouldn't take the risk on Graham's partner in the forwards.

Half Jake Green is 50-50 after a late hit in the game against Forster Tuncurry Hawks last weekend.

If he doesn't play, Scott Grant will slot into the halves role. He had been back on the bench after Luke Sprague's return to five eighth.

Sprague had about two months away from the game with a broken thumb.

Jake Kelly is in doubt with a dodgy shoulder.

Shipway was wary of the Tigers, who would be out to knock off the unbeaten team of the competition.

The Tigers game is followed by a match against Wauchope Blues to finish off the regular Group 3 season.
