St George Illawarra winger Brett Morris has revealed he came within a whisker of joining twin brother Josh at Canterbury as the tryscoring siblings prepare to face off in Friday night's NRL blockbuster at WIN Stadium.

The 23-year-old pair, sons of former Dragon Steve Morris, saw their footballing paths finally diverge when Josh joined the Bulldogs last season.

Former Dragons coach Nathan Brown struggled to tell them apart when they first hit first grade and Brett, who re-signed with the Dragons in 2009, said a chance for an identical twin to assert his own identity had been a big lure.

"(The Bulldogs) came up with a good offer and at one stage it was 50-50 so it was harder than I thought it was going to be," he told reporters on Thursday.

"I definitely thought about it but I think the way (Josh) was going over there and the way I was going here with separate clubs, forging our own identities, I think that was probably one of the things.

"I've always been a Dragons fan my whole life so I'm a big fan of loyalty and I didn't want to see myself leaving this club."

The chances of the pair playing at the same club again are now remote, said Brett who is locked up at the Dragons until the end of 2012.

"He's loving it over there, the club really look after him and he fits in well and all the players seem to like him so he's very happy there," he said of Josh.

"One day, hopefully in the future, we can get a game together but that will be a bit down the track."

The twins became the first since Kevin and Kerrod Walters in 1991 to play a Test together when they were picked to face France in last year's Four Nations tournament, and they hope to get some more game-time together this year in NSW State of Origin jerseys.

"That was an awesome experience but obviously we've played our whole lives together and we're apart now, so the only chance to play together is rep football and we'd love nothing better than to represent our state and our country together," Brett said.

The brothers are unlikely to run into each other much in Friday's second round clash, playing on opposite sides of the field, but they've made up for that with plenty of banter at home.

Especially after last year's controversial 20-18 win to the Dragons when the Bulldogs had a last minute try disallowed.

"He carries on about that all the time when we talk," Brett said.

"Obviously I've forgotten about it, that was last year.

"We don't really read into too much about what people say about us but we're a very close family, I've spoken to him every day and there hasn't been any bad words said.

"He's just asking for game-plans and stuff like that but I'm not a front-rower, I'm a winger, so I'm pretty smart, I haven't told him anything."

Less than 2,000 tickets remain for the match.
