Javier Hernandez will return to Manchester United training on Wednesday after scans revealed the striker suffered a bruised shin in United's win over Chelsea on Sunday.
Ferguson claimed Cole should have seen red, labelling the Chelsea defender "reckless". But the left-back, who was booked for the challenge, will not face a charge from the FA.
Despite fears over Hernandez's fitness for United's next Premier League game against Stoke on Saturday, the player's agent claims the striker suffered no more than "just a bump" and will return to training this week.
"[The injury is] nothing, it's just a bump, nothing more," agent Eduardo Hernandez told Telivisa. "I expect him to be training without incident on Wednesday. It looked like [his absence] was longer, they were looking for a fracture, that's why they ran those tests on him."
