English clubs discover their opponents in the UEFA Europa League play-offs
Europa League live updates
Hull had to settle for a goalless draw on their competitive European debut as Tom Huddlestone missed a penalty and a point-blank follow-up against Slovakia's AS Trencin.
The Tigers, having qualified for a first ever campaign at Europa League level by finishing runners-up in the FA Cup, should have come away from their third qualifying round first leg at Zilina's Stadion pod Dubnom with victory but will now need a result in East Yorkshire next Thursday.
An hour had gone when Shane Long was felled in the area but Huddlestone - who missed in the shootout when Spurs lost to Basel in the 2013 competition - produced a dreadful double miss.
His penalty was comfortably saved by Milos Volesak but it was the secondary attempt, grazing the bar from a couple of yards with the goal yawning, that will haunt the midfielder.
Hull will begin their debut European campaign with a tie against either AS Trencin of Slovakia or Serbia's Vojvodina.
The 2014 FA Cup finalists were in the hat for Friday's Europa League third qualifying round draw and look most likely to meet the Slovakian side, who have a 4-0 lead over Vojvodina from the first leg of their second-round tie.
Sevilla coach Unai Emery has announced he will sign a contract extension with the Spanish outfit on Wednesday, ending speculation of a possible move to AC Milan this summer.
Emery has been strongly linked with a move to the San Siro outfit to replace current boss Clarence Seedorf.
The Spanish tactician enjoyed a fantastic campaign with Sevilla, leading the Andalusian side to lift the Europa League title and finish fifth in La Liga.
Benfica XI: Oblak, Luisão, Pereira, Siqueira, Garay, Amorim, Sulejmani, Gaitán, Gomes, Lima, Rodrigo.
Sevilla XI: Beto, Coke, Pareja, Fazio, Alberto, Carriço, Mbia, Reyes, Rakitic, Vitolo, Bacca
