Justin Allgaier was fastest in the lone Xfinity Series practice session Friday at Bristol Motor Speedway.
Allgaier covered the half-mile, high-banked oval with a speed of 124.420 mph. Erik Jones was second-fastest (123.722 mph), followed by Kyle Larson (123.594), Ryan Blaney (123.515) and Austin Dillon (123.380).
Two Xfinity practices were originally scheduled, but rain washed out Friday’s morning action, including NASCAR Cup practice.
When the rain finally stopped, NASCAR officials cancelled NASCAR Cup and K&N Pro Series East qualifying for later in the day and then scheduled just one practice session for each of the three series racing at BMS this weekend: K&N (1 to 1:55 p.m. ET), Xfinity (2 to 2:55 p.m. ET) and NASCAR Cup (3 to 3:55 p.m. ET).
