The club had announced an agreement with the striker, who won the 2013 Africa Cup of Nations under the tutelage of Stephen Keshi.
Ideye joins former international teammates Ahmed Musa and Shehu Abdullahi of Kano Pillars in the Nigerian top flight.
Also, former Super Eagles defender Godfrey Oboabona remains a member of Sunshine Stars of Akure after he was unveiled in February.
Announcing Ideye’s arrival, the club will bank on the player’s experience as they hope to return to winning ways under the new manager.
Enyimba posted on their official X handle:
“We are delighted to officially announce the addition of former Super Eagles Striker Brown Ideye to our fold.
“We are expectant of the experience & professionalism he will add to our game/quest in our remaining games, this season especially under the new gaffer.”
The 36-year-old had been without a club since leaving Kuwaiti outfit Al-Yarmouk in the Summer of 2022 after he managed just eight appearances.
He began his professional career in 2006 with local club Ocean Boys in Bayelsa before moving to Europe to join Swiss outfit Neuchatel Xamax the following year.
The forward also played in France, Ukraine, England, Greece, China, and Turkey and made a fortune playing professional football.
