The Sharks will be missing six top-line players and will be hoping prop Craig Stapleton and centre Bronx Goodwin come through South Coast's Country Championships clash with Northern Rivers on Saturday unscathed.

James Keelan (knee), Matt Docker (neck), Matt Leabeater (hip), Ian Catania (hamstring) and Jai Dormer (back) will all be missing but Walsh has made no room for excuses this week.

"I'm not looking for excuses. We're leading the club championship and we've got pretty good depth in the club," he said.

"It's going to be tested this week for sure but this week's a chance for someone else to step up."

The Sharks are also coming off a tough 16-8 loss to top-of-the-table rivals Warilla last week, their second loss to the Gorillas this year, but Walsh said he hasn't had cause to question his side's premiership credentials.

"We had our chances and we probably lacked a bit of finesse close to their line and a few errors that hurt us," he said.

"I thought we played pretty well. We had them under the pump but we just didn't crack them at times when we had them in the position to put a bit of pressure on them.

"I lost all my replacements, I didn't have any left by the end.

"I'm not concerned about it at all. I'm confident we can get them."

The Superoos have notched 112 points in their past four matches and promise to pose an interesting challenge to the depleted Sharks coming off a last-start 30-28 loss to Kiama.

"I haven't watched them play this year but I believe Jono Dallas steers them around the park pretty well," Walsh said.

Berry host Gerringong on Saturday while Port Kembla will host Albion Park at Noel Mulligan Oval.

In the round's other Sunday match Nowra will be looking to upset Warilla at Nowra Showground.
