HAMPDEN league clubs are using Greater Western Victoria Rebels' bye to boost their sides.
Cobden has selected Henry Robertson - son of Maskell Medal winner Wayne - for its twilight fixture against Portland at Hanlon Park on Saturday night.
Portland has regained the services of Jamieson Ballantyne, fresh from a 21-disposal NAB League game, while South Warrnambool has welcomed back Rebels' pair Will White and Myles McCluggage.
Koroit will have three debutants - Rebel-listed Jamie Lloyd, Paddy Haberfield and Matt Bradley - for its blockbuster match against North Warrnambool Eagles, while Warrnambool has picked Reggie Mast for his first senior appearance.
Listen to this week's The Main Break podcast with Dennington's Ben Thornton:
Cobden coach Dan Casey said he was rapt to pick Robertson for his senior debut.
"He would've definitely played round one if he wasn't picked in the Rebels," he said.
"He's just clever around the goals and when he's got the footy in his hands.
"It is pretty amazing from a young 16-year-old boy. We're not expecting him to do anything amazing, just go out and have some fun."
Robertson replaces round one debutant Brad Gillingham (illness) while Liam Loubey has returned to the club from Colac. A decision is yet to be made on whether he will slot into the seniors or reserves for round two.
Portland coach Jarrod Holt said the Tigers were rapt to welcome Ballantyne and Jackson Dunlop.
They replace Tom Haylock and Ash Orchard.
"It made selection really tough after everyone played really well last week," he said.
"I can't remember it being so tough. Maybe I am getting a bit soft in my old age."
Holt said Ballantyne, who has AFL ambitions and is on Footscray's VFL list, loved donning his home club's colours.
"He is looking to pursue bigger and better things, which I am sure he will," he said. "The games he played for us last year when he was back from Rebels, he had a good impact on every game."
Warrnambool has picked Reggie Mast - a defender still eligible for the under 16s - for his senior debut against Hamilton Kangaroos.
Blues coach Ben Parkinson said Mast's efforts in their practice matches had impressed.
The loss of backmen Jordy Foott (hamstring) and James Chittick (concussion) paved the way for the GWV Rebels-listed under 16 player.
"He's played on 'Rowy' (Jason Rowan) and 'Moo' (Sam Cowling) in match-play so he knows what he's up against," Parkinson said.
"He has a really decent frame on him for an adult, let alone a 15-year-old kid.
"We don't want to put him to full-back but I am sure he'll hold his own on whoever he lines up on.
"He is eager to learn and improve as much as he can."
The Blues also welcome back experienced pair Mitch Bidmade and Brad Bull, who were both unavailable round one. Josh Irving was omitted.
Koroit coach Chris McLaren said the Saints were backing three first-gamers against the dominant Eagles.
Lloyd, Haberfield and Bradley come in for Will Petersen (concussion), Jack O'Sullivan (unavailable) and Tim Martin (unavailable).
"'Lloydy' is a utility and very versatile," McLaren said.
"He is going to be a really good player and he's a great trainer.
"Paddy hasn't played a lot the past few years with the COVID year and then he had an ankle reconstruction and other injuries.
"He's a really talented player but has just had a bad run. The (Let's Talk Cup) under 23 comp was great for him in terms of the training we did for it; he jumped on the coattails of some of our great trainers and had a great summer.
"Matt has crossed over from South Warrnambool. He played under 18s last year and is mates with a lot of players playing seniors in our team like Mac Petersen, Paddy O'Sullivan and Tom Baulch.
"He had his first proper pre-season. He's done a lot of work with our key forwards and key backs - he's a big boy, he's six-foot-three.
"He played key forward last week in the reserves and took some really strong contested marks so we could use him at both ends at the weekend."
