Bloods coach Jeff Brennan announced the signings of the trio on Wednesday and is excited by what all three bring to the Bloods.

"Jones is six-foot-six and comes with a good background of football history," Brennan said.

"He has played a couple of years of TAC Cup at the Calder Cannons and three years at St Bernard's in the A Grade Amateurs, so he has a good record.

"We'll use him in the ruck and up forward and he will be a great addition for us."

Postle will play full-back for the Bloods.

"He has been an inter-league player with both North Central and Loddon Valley and is just a fantastic player," Brennan said.

"There's big wraps on him."

Postle is a premiership player with Wedderburn, having played in the Redbacks' 2011 grand final win over Wycheproof-Narraport.

Sweeney will provide the Bloods - who this year missed the finals for the first time since 2004 - with versatility.

"Sweeney can play anywhere... he can play key position, flanks, wings, through the middle of the ground," Brennan said.

"He has enormous flexibility."

Like Jones, Sweeney has played A Grade Amateurs with St Bernard's.

The three were all part of Newbridge's 2012 Loddon Valley Football League grand final loss to Bridgewater.

"We think they are going to be three fantastic additions for us," Brennan said.

"They've all got plenty of size about them and are really good blokes, so they will be a good fit for the club."

The Bloods are into their fourth week of pre-season training.

"Training is going really well," said Brennan, who has taken over from Rick Coburn as South Bendigo coach.

"The condition the players all came back in was great and the fitness levels are all good at this stage."

The appointment of Brennan is part of a fresh start for the Bloods.

"There's a freshness through the place with our football department and match committee," Brennan said.

"It has presented as a really clean start for the club and the players and we're looking forward to the challenge of hopefully, being much improved next year."

The Bloods are fixtured to open the 2014 season with a clash against QEO co-tenant Sandhurst on April 5.
