Crouch won 31 disposals, 11 clearances and six tackles in his second straight SANFL game. A hamstring injury plagued him in the pre-season.

Draftee Jordan Gallucci hurt his calf in the second term and sat out the rest of the match.

Gallucci was selected at No. 15 last year and is a midfielder with serious speed.

Tall targets Harry Dear (3.7) and Elliott Himmelberg (3.0) hit the scoreboard while Myles Poholke kicked two goals straight.

Harrison Wigg was excellent out of defence with 30 disposals and seven inside 50s.

State league affiliate: Collingwood (VFL)
This weekend: Coburg v Collingwood - Saturday, April 15, 2.40pm, Piranha Park

Big-name recruit Daniel Wells put himself in the mix for selection for Anzac Day after a successful return from a calf injury.

The 32-year-old played most of the game, running through the forward line and in the midfield, with his class apparent whenever he touched the ball.

Suspended midfielder Jordan De Goey was one of his side's best in his return from a broken right hand suffered in a bar fight.

De Goey can play in the VFL but will not be available for selection at senior level for the next two weeks.

He booted three goals and his strength was obvious at stoppage situations.

"He was lively. I'm enjoying the three weeks' suspension on my behalf. Clearly he's a good player and … he's just one of those guys we're missing out there at AFL level," coach Jared Rivers said.

Dropped forward Chris Mayne booted two goals and worked hard up the ground.

"His energy around the forward half (was good) and he kicked a couple of vital goals for us late," Rivers said.

Josh Daicos displayed the class that Magpies fans were hoping to see and finished with two goals.

Backman Matthew Scharenberg was very good and was influential in a couple of contests late as his side hung on to beat Coburg, 9.10 (64) to 9.8 (62).

Key defender Sam McLarty was hurt in a marking contest and sported a limp after the game while Brayden Sier suffered a head knock.

State league affiliate: Essendon (VFL)
This weekend: Sandringham v Essendon - Saturday, April 15, 2pm, Trevor Barker Beach Oval

Rookie Ben McNiece was one of Essendon's best in its narrow round one loss to Sandringham.

The 25-year-old, who was signed from Essendon's VFL list at the end of last season, was polished in defence with 23 disposals and nine marks.

Essendon VFL coach Paul Corrigan praised the Category B rookie.

"He was really controlled down back, he generated some really good ball movement for us when we needed it," Corrigan said.

"Heath Hocking (29 touches) also did a lot of work inside for us and was really strong around the contest."

Aaron Francis played both forward and in the middle, finishing with a goal, seven tackles and six marks.

Craig Bird was also busy with 23 disposals.

Former North Melbourne forward Aaron Black picked up 22 disposals and a goal while draftee Esava Ratugolea slotted three himself.

Rhys Stanley finished with 28 hit-outs and Wylie Buzza had 17 as Geelong ran out 14.16 (100) to 10.15 (75) winners.

State league affiliate: Gold Coast (NEAFL)

Returning midfielder Pearce Hanley injured his ankle and finished the game in a moon boot as the Suns beat Aspley by 14 points on Saturday at South Pine Sports Complex.

Hanley was making his return after he spent a few weeks in Ireland for the funeral of his younger brother Tommy.

He collected 11 disposals and kicked a behind before being forced off the ground.

Former Hawk Mitch Hallahan suffered a hamstring injury. Both players were injured in the first half.

Hard nut Matt de Boer picked up 24 disposals and two goals on limited game time in his return from a hamstring injury as the Giants lost to Canberra by 16 points at Alan Ray Oval on Saturday.

The former Docker played about 65 per cent of the game, mostly in the midfield but also up forward, and impressed coach Brad Miller.

"What he gave us from a leadership point of view, and the way he attacks the contest, was terrific," Miller told AFL.com.au.

Draftee Harry Perryman won 26 disposals and kicked three goals. He came to the club as a half-back but has played on the ball and drifted forward at times against Canberra.

"It's more his composure in traffic that's really making a difference. He's shown a lot over the first few weeks," Miller said.

Rookie Dan Lloyd notched up 36 disposals. Lloyd was originally an explosive forward but his toughness has been important around the footy.

Harrison Himmelberg copped a heavy knock to the ribcage but fought through to collect 21 disposals.

Former Western Bulldog Koby Stevens racked up 28 disposals while Darren Minchington had the same number, along with four goals.

Omitted premiership player Caleb Daniel was among Footscray's best as the Dogs fell to Box Hill by two points at Whitten Oval on Friday afternoon.

It was a similar story for fellow premiership player Shane Biggs, whose rebound off half-back improved as the match went on. 

Stewart Crameri, who has been struggling with a hip injury, sat out the second half and booted a goal in a quiet game.
