ENGLAND forward Tom Burgess has followed older brother Sam in pledging his future to South Sydney until the end of 2023 but the future of his twin George remains uncertain.

The Rabbitohs announced a four-year contract extension for ex-Bradford Bulls prop Tom, 26, who was the last of the four Burgess brothers to make the move to the NRL in 2013.

"Souths is all I know and I'm really pumped to be signed up long-term now," he said.

"They gave me a chance when I came to Australia for the first time and six or seven years down the track I'm still enjoying my football here and I wouldn't want to play anywhere else.

"I've loved being at the club from the start. Having family here helped and I suppose it is my extended family now, but that's how I see the Rabbitohs and I'm really pleased to extend on and hopefully I finish my career here."

George's contract runs out this season and he reportedly rejected an offer to join Parramatta earlier this year.
