Porto captain Jackson Martinez has been named in the starting lineup for the first leg of his side's Champions League quarter-final with Bayern Munich.
The Colombian international had been a serious doubt with a hamstring injury, but he has been passed fit to lead the attack.
Bayern have also had a number of problems, with Franck Ribery and Arjen Robben both ruled out through injury, while Bastian Schweinsteiger misses the game with flu.
However, Robert Lewandowski, Mario Gotze and Thomas Muller start up front, with Xabi Alonso back in the midfield after sitting out a suspension.
Porto: Fabiano, Danilo, Maicon, Martins Indi, Alex Sandro, Casemiro, Herrera, Torres, Quaresma, Martinez, Brahimi
Subs: Helton, Reyes, Neves, Evandro, Hernani, Quintero, Aboubakar
Bayern Munich: Neuer, Dante, Thiago, Boateng, Lahm, Bernat, Alonso, Rafinha, Gotze, Muller, Lewandowski
Subs: Reina, Lucic, Pizarro, Gaudino, Rode, Badstuber, Weiser
