The Brisbane Broncos have confirmed that back rower Matt Gillett will undergo shoulder surgery on Wednesday morning for recurring neck fractures suffered earlier in the season.

The 30-year-old will take approximately six months to recover from the shoulder reconstruction, effectively sidelining him until club's 2019 trial matches.

"The shoulder has been an ongoing issue for Matt for the last couple of months," said Broncos' high performance manager Jeremy Hickmans told

"We had to wait and see what was happening with his neck injury, as obviously that was the priority.

"When it became apparent he was not going to play again this season, we sent him for a scan on his shoulder.

"From that scan the decision has been made to go ahead with the shoulder surgery.

"If all goes as expected with his recovery, we would hope to see Matt back on the field during next year's trial match period."
