As will Bulldogs legend and six-time premiership winner John Deverell.

Three brothers, Deverell's sons Lachlan, Corey and debutant Harrison, will line up in Reiman's side to tackle the Maitland Saints at Max McMahon Oval in the last round of Black Diamond Cup.

It will mark the first time the trio have played together in the AFL Hunter Central Coast top grade, making it a special occasion for the finals-bound Bulldogs.

"To have all three brothers together in first grade will be a nice moment for the team, the club and the family," Reiman said.

"It's nice to have the chance to see it happen before I finish up."

Reiman, who will step down as head coach at the end of 2019 after four years in charge at Warners Bay, said the youngest Deverell sibling Harrison had "earned his debut" through strong performances in reserves.

"We've still got a few blokes out so I thought why not give a young guy a go," Reiman said.

Harrison has been named on the interchange bench and Lachlan at halfback while Corey is listed as a ruckman.

Key trio Riley Warner, Matthew Spinks and Nick Turner all remain sidelined for the Bulldogs with ankle injuries.

Warner, who also dislocated his knee earlier in the season, and Spinks are expected back the following weekend for Warners Bay's elimination semi while Turner is "doubtful".

"If it was finals this week than Warner and Spinks would have probably played but we want to have our strongest possible team next week so we've opted to rest them rather than risk it," Reiman said.

The Bulldogs welcome back Lincoln Stewart, Jack Downing and Luke McKenna.

Warners Bay (32 points) are sitting sixth on the competition ladder, but can jump to fifth if they beat the Saints on Saturday and Singleton (36) lose to second-placed Newcastle City (60) at Rose Point Park.

This would alter who plays third-placed Cardiff (52) and fourth-placed Killarney Vale (44) in the opening round of play-offs.

Jack Pratt (striking) is out suspended for Cardiff, who host Wyong Lakes (12) at Pasterfield Sports Complex in round 18.

Killarney Vale, who are away to leaders Terrigal Avoca (64) at Hylton Moore Oval, are minus Scott Reed (study) for this weekend and next.

Nelson Bay (12) are at home to Gosford (12) at Dick Burwell Oval with both sides keen to avoid the wooden spoon.
