Injured British Touring Car Championship driver Jeff Smith will be replaced by his son Brett at the Eurotech Racing squad for the remainder of the 2017 season.
Jeff Smith was involved in a multi-car pile-up during qualifying for the previous round of the championship at Croft.
He has chest and shoulder injuries that have ruled him out of driving for the rest of the campaign.
Son Brett will now take up his seat alongside Jack Goff in the two-car team, starting at the next round of the season at Snetterton on July 29/30.
The new recruit, who is currently leading the Mini Challenge in his second season in the series, will test the Eurotech Honda Civic for the first time at Snetterton during the championship's official test session next week.
"I am naturally extremely disappointed for my season to be ended in this way," said team principal Jeff Smith, who returned home from hospital last week.
"Having assessed a number of driver options the team are in agreement that Brett gives us the best opportunity to provide a strong second half to the season."
