Goalkeeper Ederson has been named in Manchester City's squad for their opening Champions League group game against Feyenoord on Wednesday.
The Brazilian, 24, needed eight stitches in his face after being caught by a high boot from Sadio Mane during the 5-0 win over Liverpool on Saturday.
But he trained on Tuesday wearing a headguard to protect the affected area.
He could be involved on Wednesday but, if not, Claudio Bravo is set to deputise.
Ederson required lengthy treatment and was carried off on a stretcher after the 37th-minute collision with Mane, who was sent off.
He returned to watch the final stages of his side's victory, and City boss Guardiola said after the game he hoped Ederson "can come back soon".
Liverpool have since appealed against the length of Mane's three-match ban.
