Busch has a track-record 21 victories at BMS with nine of those coming in the Xfinity Series. He has four straight Bristol wins, including a sweep of Truck Series, Xfinity Series and Monster Energy Cup Series races last August. With no Cup Series drivers allowed in April's Fitzgerald Glider Kits 300, Ryan Preece drove Busch's No. 18 Toyota to another BMS win.
Elliott, who picked up his first Cup Series win at Watkins Glen two weeks ago, will be driving the No. 23 GMS Racing Chevrolet. The second-generation star has four top-10 finishes in four Xfinity starts at Bristol, including a third-place finish in the 2014 Food City 300.
Other Cup Series drivers entered in the race include Joey Logano, Kyle Larson and Ty Dillon.
Logano has two NASCAR Cup Series wins at Bristol and he also has two BMS victories in the Xfinity Series. He led all 300 laps of the 2015 spring race, and has finished in the top 10 in his last eight Bristol starts.
Larson is remarkably looking for a first Bristol win in any series. He finished third in last August's Food City 300 after leading 200 laps. He has three runner-up finishes in Xfinity races at Bristol, each time finishing second to Busch.
Dillon has eight top-10 finishes in nine BMS Xfinity races. Despite that record, which includes four top-five finishes, he has led just one lap at Bristol. He will be in the No. 3 Chevrolet that his older brother, Austin, drove to victory in the 2016 Food City 300.
Points leader Christopher Bell led the Xfinity Series regulars. A teammate to Busch at Joe Gibbs Racing, Bell has a series-best four wins this season. He finished 29th in April after getting caught up in a crash.
Elliott Sadler, currently tied for second in the points, has a Cup Series win and two Xfinity Series victories at Bristol. Daniel Hemrick, who is tied with Sadler, is still looking for a first career win. But, he's a definite threat at Bristol after finishes of fifth, seventh and third in three starts.
Justin Allgaier, who won the series' most recent race at Mid-Ohio, took the Bristol spring race in 2010. Other contenders include Brandon Jones in a third Joe Gibbs Racing car and Austin Cindric, who is Logano's teammate in a Team Penske Ford.
