NASCAR issued penalties Tuesday to two Xfinity Series teams for infractions that incurred during this past weekend’s racing action at Indianapolis Motor Speedway.
The more serious infraction -- a loss or separation of an improperly installed rear axle -- was assessed to Daniel Johnson, crew chief for Xfinity Series driver Tommy Joe Martins, after the axle broke during Saturday’s race on the IMS road course.
Johnson has been suspended for the next Xfinity Series points event, which will be the first race of this weekend’s Xfinity doubleheader at Kentucky Speedway (Thursday at 7:30 p.m. ET on FS1).
The other penalty was assessed to Brian Wilson, crew chief for Austin Cindric, due to an unsecured lug nut. Wilson has been fined $5,000.
There were no other penalties issued.
