Rolf Gundersen/Fredrikstad FK
West saw action in the first leg
Brad Friedel and Blackburn try to hold onto their one goal lead in Finland against MyPa, while Brian West and Fredrikstad attempt to knock out Charlie Davies and Hammarby.
Fredrikstad - Hammarby
Fredrikstad only need a 1-0 result against Swedish club Hammarby to qualify for the next round in the UEFA cup.
Playmaker Raymond Kvsivik who scored FFK's only goal in Sweden, was rested on the weekend, and should be back into the Norwegian club's starting lineup.
American forward Brian West also sat out, but will most likely start off the bench in favor of Gardar Johanssen and Tarik Elyounoussi.
Davies on the other hand will certainly not figure in the Hammarby starting eleven, after being dropped from the squad for last weekend's clash against Brommapojkarna.
The Swedish club will look instead to Under 21 star Erkan Zengin along with first leg scorers Sebastian Castro-Tello and Brazilian Paulinho in attack.
Aalborg BK - HJK Helsinki
Captain Danny Califf will anchor the defense on Thursday as Aaborg look to recover from their 2-1 loss to HJK in the UEFA cup qualifying second round.
Midfielder Kaspar Risgård pulled a goal back for the Danish club in Helsinki, before HJK Seirra Leone forward Kabba Samura scored his second of the night early in the 56th minute to secure the win for the Finnish squad.
Aaborg come into the match with a psychological edge having won this weekend 2-1 away at Esbjerg while HJK only managed a 1-1 draw at home to FC KooTeePee .
Blackburn Rovers - MyPa
Blackburn host MyPa in the second leg match after skating away from the first encounter with a one-goal victory over the Finnish club.
After missing the first leg, Benni McCarthy should be back in the lineup and will pair up with Roque Santa Cruz as the English club only need a draw to advance to the next phase of the competition.
MyPa has no real injury concerns, but morale is not high after a 1-0 loss to fellow Veikkausliiga club Vaasan Palloseura over the weekend.
Brann defender Ramrio Corrales is still recovering with a knee injury and will not make the trip to Lithuania to face FK Suduva following their 2-1 win at home in Bergen.
Oguchi Onyewu will be rested in Standard Liege's return match against Käerjeng after the Luxembourg club fell 3-0 at home to the top-flight Belgian squad in the first leg.
Gabriel Ferrari was not picked in Sampdoria's 22-man squad to face Hajduk Split on Thursday. The Genoa club won the first leg 1-0 in Croatia.
