London Irish have confirmed Australia international James O'Connor will leave the club at the end of the season after completing his six-month contract.
The news comes a day after the club announced England winger Marland Yarde will be joining Harlequins next season.
O'Connor, 23, is keen to play in the Super Rugby competition in the build-up to the 2015 World Cup.
The full-back could have signed a short-term deal with the Exiles but may now choose to play for a French side.
"I have thoroughly enjoyed my time at London Irish and I'm looking forward to the next few months," said O'Connor.
"The club welcomed me in with open arms last year in what was a difficult time and have been brilliant to me during my time so far.
"I've learnt a great deal both on and off the field and will leave at the end of the season with great memories and mates too."
O'Connor joined the Exiles in October after the Australian Rugby Union terminated his contract following a string of off-field incidents.
He told BBC Berkshire in January he intended to try and win his international place back.
