Rebels near full strength for season-defining clash with desperate Chiefs

Melbourne have reinstalled their premier halves pairing Will Genia and Quade Cooper but have two Wallabies omissions for their must-win Super Rugby match against the Chiefs.

The Rebels have left out Test lock Adam Coleman (shoulder) for Friday night's AAMI Park match while winger Jack Maddocks has made way in a backline reshuffle.

Reece Hodge will replace Maddocks and Tom English will partner Billy Meakes in the centres, while Wallabies winger Marika Koroibete is also back in the starting side.

Melbourne coach Dave Wessels said Maddocks had a few niggles and also needed a mental refresh.

"He's a big part of our team but at this stage he's played a lot of rugby and there's some warning signs his body was starting to feel a bit fragile," Wessels said.

The Rebels currently sit eighth - and must at least hold that spot through the final round to play in their first finals campaign.

"It's showtime for us," said Wessels.

"We've got an opportunity to do something for the club that we've never been able to do so I think guys are pretty motivated."

The Rebels were crushed 66-0 last round by the front-running Crusaders but Wessels said his team had quickly put that "embarrassing" loss behind them.

Resting Genia and starting Cooper on the bench last round, Melbourne were always targeting the Chiefs match as the one to cement a playoff berth.

Currently 11th, the Chiefs are also in the finals hunt and require a bonus point win to assure themselves a spot in the top eight.

"When we first looked at the calendar this was a game that we thought we'd want to target," Wessels said.

"It's an opportunity to respond from last week ... I feel like we are going to play well on Friday night."
