Paraguay will be without attacking duo Roque Santa Cruz and Derlis Gonzalez when they meet Peru in the Copa America third-place play-off.
Ramon Diaz's men are aiming to bounce back from a humbling 6-1 semi-final defeat to Argentina and must do so with a reshaped forward line.
Diaz's forward woes do not end there, with Nelson Haedo Valdez nursing a thigh problem, while defender Bruno Valdez is suffering from a similar complaint.
Guerrero now has 24 international goals, leaving him only two behind Peru's all-time record scorer Teofilo Cubillas.
Peru coach Ricardo Gareca does not expect Paraguay's chastening experience last time out to have much impact on their performance.
"Paraguay are always dangerous, regardless of their thrashing," he said. "It's going to be complicated game no matter the [injury] absences."
Diaz recognises that his players must be on their mettle to avoid further disappointment.
"We know that Peru have shown that they are in the process of growing and I'm sure both teams are going to give their best to finish in third place," he said.
