The 25-year-old England international was sentenced at Birmingham Magistrates’ Court on Tuesday, after previously pleading guilty to two charges, including one linked to the incident in which his 4×4 hit two parked vehicles in Dickens Heath, Solihull, West Midlands.
A judge was told that a witness said Grealish smelled of “intoxicating liquor” and was slurring his words immediately after the crash on March 29.
Grealish was involved in the incident less than 24 hours after issuing a Twitter video message urging people to stay at home to save lives and protect the NHS.
He also pleaded guilty to a separate offence of careless driving after prosecutors said an unmarked police car spotted him driving at more than 90mph along the M42 at “close to an intimidating distance” on October 18.
Grealish was also ordered to pay costs of £220 and a victim surcharge of £181, taking his total in costs and fines to £82,900 – all payable within seven days.
The winger will also have to apply for a new licence, once his ban ends.
