Cristiano Ronaldo will play against Manchester United as he could escape further extended ban.
Ronaldo saw red after appearing to pull the hair of Valencia defender Jeison Murillo during Wednesday night's clash.
UEFA sources have suggested that the mandatory one-game suspension is unlikely to be extended to a two or three matches, so the star will face Manchester United on October 23.
There is no right of appeal over the one-game ban but sources say that disciplinary officials, who have viewed television footage of the incident, do not regard Ronaldo’s indiscretion as worthy of an increased punishment.
