Sepp Blatter will meet with African football leaders in Johannesburg this weekend, the latest stop in his re-election campaign.
The meeting has been called mainly to discuss a lasting legacy for the 2010 World Cup.
But it will give the Fifa president a final opportunity to seek support in a key continent before the vote on 1 June.
The 75-year-old Swiss is seeking a fourth term as head of world football.
The Council of Southern African Football Associations (Cosafa) says Blatter will meet with representatives from four of the five regional African federations on Saturday.
However, his Qatari challenger Mohamed bin Hammam is believed to have significant support among Africa's 53 federations - a quarter of Fifa's total membership.
