The XFINITY Series Fitzgerald Glider Kits 300 went back to green after a lengthy red flag induced by rain at Bristol Motor Speedway. The action was put to a halt on Lap 150 with a yellow flag, followed by a red flag on Lap 162. The time of the red flag officially lasted one hour, 38 minutes and 52 seconds.
Prior to this, NASCAR briefly lifted the red flag only to return to red-flag conditions minutes later with more rain hitting the .5333-mile track.
As the leaders pitted, Daniel Hemric, Blake Koch, Brandon Jones, Brendan Gaughan and Elliott Sadler stayed out to hold down the top five spots, and lead the field back to green on Lap 168.
The event originally got underway at 1:03 p.m. ET with Larson and Austin Dillon starting on the front row after scoring the top-two fastest qualifying lap times Saturday morning.
Larson topped Stage 1, which ended under yellow after Ryan Reed brought out the caution in its waning laps after clipping the wall and losing a tire. Reed briefly wheeled his No. 16 Ford to pit road, but ultimately brought it to the garage with heavy damage, done for the day.

The XFINITY Series Bristol race marks the second Dash 4 Cash event of 2017. JR Motorsports teammates Justin Allgaier and Cole Custer are eligible for the $100,000 bonus after scoring the top-two spots among XFINITY Series regulars at the end of Stage 1 as well as Hemric and Gaughan after finishing first and third (the two highest-placing XFINITY regulars), respectively, in Stage 2. Hemric earned a playoff bonus point with his Stage win, should he qualify for the 12-driver playoff field.
Allgaier won the first Dash 4 Cash race at Phoenix Raceway. The final two legs will be at Richmond (April 29) and Dover (June 3).
