Ulster are set to confirm the signing of Wallaby fly-half Christian Leali'ifano ahead of the 2017-18 PRO14 season.
The deal is believed to be a short-term contract from the start of the PRO14 season until February 2018 when the Super Rugby season kicks off for the ACT Brumbies.
The 29-year-old has won 19 caps for the Wallabies and recently made an inspirational recovery from leukaemia.
Ulster are short of options at out-half following Paddy Jackson's pending legal proceedings and the news comes shortly after Ulster Chief Executive Shane Logan announced last week that the Irish province were actively looking to recruit a fly-half before the start of the season.
Leali'ifano was diagnosed with leukaemia last year while playing with the Brumbies and made a return in the Super Rugby knock-outs leuthis season, less than a year after being diagnosed with the disease.
Ulster start their Pro14 campaign against South African newcomers Cheetahs at Kingspan Stadium on Friday, 1 September.
