The Super Eagles of Nigeria and Tanzania head into the half-time break level at 1-1 after an entertaining opening 45 minutes in Uyo.
Nigeria made a flying start, taking the lead just three minutes into the encounter through Alhassan Yusuf.
The goal followed an excellent team move, with Akor Adams winning possession before finding Ademola Lookman, who cleverly laid the ball into the path of the advancing Yusuf to slot home.
However, Tanzania responded positively and restored parity in the 32nd minute through Alphonce Msanga, punishing Nigeria after the hosts failed to protect their early advantage.
Despite enjoying more possession and controlling significant portions of the game, Nigeria have been unable to turn their dominance into another goal.
Both teams now head into the dressing rooms with everything to play for in the second half.
The Super Eagles will need greater attacking precision and defensive concentration after the restart to reclaim the lead.
