Uganda's Argentine coach Pedro Pablo Pasculli may be absent from their crucial Nations Cup tie in Ghana on Saturday.
Pasculli left for Argentina on Saturday after receiving news that his 83 year-old father was very ill and had asked to see him.
"I feel terrible, because I have not seen him for over two years now.
"I only pray that I find him still breathing," said Pasculli who took over as coach of the Cranes a month ago.
Uganda must beat Ghana's Black Stars in Kumasi to be sure of a ticket for Tunisia 2004, as they lost 1-0 to Rwanda in their home match of 7 June.
The Cranes have not qualified for the Nations Cup since 1978.
"Joining the team in Ghana [for the match] will depend on the condition of my father's health," said Pasculli.
Assistant coach Leo Adraa in now in temporary charge of the team.
Adraa guided Uganda's U-23 team to fourth place at the 1999 All Africa Games in South Africa.
Meanwhile, three overseas-based players have been invited to strengthen the squad.
They are: Irish based Charles Livingstone Mbabazi, Suleiman Tenywa with US Major League Soccer club Dallas Burn and Ibrahim Sekajja, who plays for Ferro Carril Oeste in Argentina.
The FA said the government had issued Ugandan passports to Congolese born defender Bana Zidane and Pitchen Bajope, which makes them eligible for international selection.
