Grealish, of Barnt Green, Worcestershire, was also ordered to pay £110 in court costs and a victim surcharge of £266, leaving him with a total bill of £1,042.
A charge of failing to give information to the police relating to the identification of the driver was withdrawn.
After confirming the maximum penalty for the offence was £1,000, reduced to £666 after a guilty plea, his barrister John Dye said: “He can afford to pay that figure.
“I am asked to apologise on his behalf. It was a mistake.”
He also said Grealish meant no disrepect by not appearing in person.
