Ulster have pulled out of a proposed deal to sign Glasgow Warriors forward Leone Nakarawa following an issue with his medical.
Named European Player of the Year in 2018 while at Racing 92, Nakarawa had agreed a one-year deal last January and would have been a significant addition to the province's ranks.
The Fijian international, 32, can play at lock or back row.
However, it emerged on Thursday that there was an issue with his medical at the weekend which means the move will not now go ahead.
"We can today confirm that, on receipt of a detailed medical report following an examination by the club at the weekend, Leone Nakarawa will no longer be joining Ulster Rugby for next season," a club statement said.
"This outcome is disappointing for both the player and Ulster Rugby, however, we will continue to build strongly with our preparations for next season.
"We wish Leone the very best for the future."
