The XFINITY Series Dover race postponement -- due to weather -- left teams scrambling to assemble its lineups Saturday afternoon with playoff chances on the line.
Chase for the NASCAR Sprint Cup contenders, Kyle Busch, Joey Logano and Austin Dillon were expected to perform double-duty, but with both races now on Sunday, teams had to reassemble its lineups so the trio could focus on their main event -- the first elimination race in the Chase.
Drew Herring will wheel the No. 18 Joe Gibbs Racing Toyota for Busch, while Ryan Blaney will sit behind Team Penske's No. 22 Ford for Logano and Regan Smith is set to replace Dillon in the No. 2 Richard Childress Racing Chevrolet, according to multiple reports.
Busch enters the Sprint Cup Citizen Soldier 400 (2 p.m. ET, NBCSN, PRN, SiriusXM NASCAR Radio) fourth on the Chase Grid and, just a few spots behind, sits Logano in sixth. Dillon is currently 14th, five points below the cutoff.
Friday's NASCAR Sprint Cup Series qualifying session at Dover International Speedway was canceled because of rain. The lineup was set according to the NASCAR rule book, putting Brad Keselowski on the pole for Sunday's Citizen Solider 400 (2 p.m. ET, NBCSN, MRN, SiriusXM NASCAR Radio).
Martin Truex Jr., in the No. 78 Furniture Row Racing Toyota, will start on the front row alongside the No. 2 Team Penske Ford.
"We earned it because, obviously, we've been having a great season, maybe not with what we've done on track today, but with what we've done throughout the course of the year in scoring a lot of points and winning races," Keselowski said.
"But it's certainly still something to be very proud of, to be this far into the season and be in the points lead. These are the perks you get when you're in that position. We'll take it, and of course, being up front gives us a very advantageous pit road selection for this race, which I think is very critical."
The three-round, group qualifying effort at the 1-mile concrete oval was scheduled to begin at 3:40 p.m. ET, but wet weather delayed that schedule. This marks the third straight Sprint Cup event at Dover that qualifying has been washed out by rain.
Kevin Harvick, Paul Menard, Michael Annett, AJ Allmendinger and Jeff Gordon will select Sunday's pit stalls last for receving a fourth written warning from NASCAR.
Sunday's Citizen Soldier 400 is the final event in the 10-race Chase's opening Round of 16. The results will determine which 12 drivers remain championship-eligible and which four fail to advance in the postseason.
Kyle Larson holds the final transfer spot entering the Dover race with a five-point lead over Chip Ganassi Racing with Felix Sabates teammate Jamie McMurray and Richard Childress Racing's Austin Dillon. Larson will start 12th, with McMurray and Dillon directly behind him in 13th and 14th, respectively.
The second of two NASCAR XFINITY Series practices was cut short by rain. The practice lasted about nearly half of its scheduled 85 minutes before being put on hold and eventually called due to rain.
