Toronto FC:
Looks like another back five for Toronto FC, with Ashtone Morgan at centre-back. Beyond that, my best guess is that TFC are using a 4 man midfield, with Laryea and DeLeon on the wings, and Jozy Altidore as the lone forward.
Despite being listed in the starting lineup, Jozy Altidore isn’t out for warmups, and Jordan Hamilton is warming up with the starters. (Edit: He’s now emerged from the tunnel, about 20 minutes after everyone else - not sure what his status is)
Michael Bradley isn’t even in the 18, and neither is Jonathan Osorio.
