Six cars were involved in the incident, which unfolded in the closing laps of the ToyotaCare 250.
"We got hit from behind and that sent us up into him," Byron said Tuesday after wrapping up testing at Charlotte Motor Speedway. "Just not a good situation. You never want to be in a situation like that."

Suarez, the 2016 series champion and now a full-time competitor in the Monster Energy NASCAR Cup Series for Joe Gibbs Racing, posted on Twitter the following day "Good job @WilliamByron for making a mess on yesterday’s race … today is a new day with a strong race car."
The two drivers were running inside the top 10 when the accident occurred on the first lap of a restart. Suarez was able to continue and eventually finished 21st while Byron was unable to return and wound up 30th.
Byron said he and Suarez "have talked" since the incident.
"Really, we were just following each other into the corner double-file, everyone was jockeying for the restart; we got nudged and hit into him and that ruined our day, too," Byron said. "Not a good situation but hopefully we can rebound from that for Talladega. It’s going to be a totally different environment there and we’ll just see what happens."
The series moves to Talladega Superspeedway this weekend for Saturday’s Sparks Energy 300 (1 p.m. ET, FOX, MRN, SiriusXM NASCAR).
Byron won seven times last season in the NASCAR Camping World Truck Series for Kyle Busch Motorsports. He is competing for Sunoco Rookie of the Year honors this year in the XFINITY Series for JRM.
The 30th-place finish has been the only blemish on an otherwise solid season thus far for the 19-year-old. Through eight races, he has posted five top-10 finishes and is third in points, trailing teammates Elliott Sadler and Justin Allgaier.
"I think he’s done a great job," Allgaier said of Byron. "Coming in, he’s asked a lot of great questions and been very open to learning.
"There have been a lot of weeks that he’s been kind of the flagship for our company. Especially the mile and a halves, he’s been lights out."
