Atlanta will use the same lineup as their last game, as Gerardo "Tata" Martino has used a similar group throughout the playoffs.
Expect the group to play in the 5-3-2 that has become a mainstay for the Five Stripes.
Portland, meanwhile, welcome back defender Larrys Mabiala after he recovered from his ankle injury suffered in the Western Conference Championship. Mabiala replaces Bill Tuiloma, who moves to the bench.
While there had been speculation Timbers head coach Giovanni Savarese could opt for a five-man defense, this appears to be a 4-2-3-1 formation that has been primarily used of late. Also of note, Zarek Valentin retains his starting spot at right back, over Alvas Powell, who is on the bench.
