UEFA will hold tomorrow's draw for the group stage of the Champions League with one of the qualifying matches still to be played.
Sevilla's second leg against AEK Athens was postponed following the sudden death of the Spanish club's 22-year-old midfielder Antonio Puerta at the weekend.
UEFA are to decide today how to accommodate both clubs in the draw despite the fact their coefficients mean that, under normal circumstances, the clubs would be in different seeding pots.
Sevilla hold a 2-0 lead from the first leg and with a coefficient of 87.37 would be among the second seeds, while the Greek side's coefficient of 36.41 would place them in the bottom group of seeds.
It is likely that UEFA will decide that in the unlikely circumstances that AEK overturn Sevilla's first-leg advantage they would assume the Spanish club's position among the second seeds.
Sevilla, the UEFA Cup winners, are expected to confirm that they will play in the Super Cup match against Champions League winners AC Milan in Monaco on Friday night.
UEFA general secretary David Taylor said: 'The draw will take place tomorrow at 1800CET - as scheduled.
'There are additional complications this season related to the tragic and unforeseen circumstances that caused the postponement of the AEK Athens v Sevilla match.
'This means that both clubs will be `provisionally' entered in this season's competition.'
