Onuigbo last played for T&T Hanoi of Vietnam before crossing to Dolphins for the 2012/13 football season.
Ifeanyi Frederick Onuigbo started his football career with Heartland in 2007 but then moved to Sudan to play with Al Hilal one year later.
At Hilal he managed five goals from twelve games and moved on again, this time to Ahly Benghazi in Libya where he played for three seasons before moving on to Hanoi T&T in Vietnam in 2012.
The Lagos-born striker has now pitched his tent with Dolphins at least for the next season since he signed a year's deal.
“We expect him to give his best and not jettison the team at the slightest opportunity,” head of Dolphins' technical crew, Stanley Eguma said.
“Part of the agreement we had with him was that he will stay with us for one season except of course there is an arrangement where the management of the team grants him permission to travel,” Eguma said.
It is very likely that Onuigbo will play Wednesday’s League match in Port Harcourt between Dolphins and Shooting Stars.
