As a result, he replaced Caesar Bacarella in the No. 90. Tony Furr, who was going to be Pardus's crew chief when he was in the No. 91, made the move with him, replacing Eddie Troconis. Dan Pardus B.

Notes
Changes Teams On September 22, 2020, Kaulig Racing owner Matt Kaulig revealed on reporter Kelly Crandall's podcast that he hoped that his team would expand to three full-time cars plus one part-time car for the 2021 season. The team did end up expanding to three full-time cars, as the No. 16 of A. J. Allmendinger will go from part-time to full-time. In terms of the fourth part-time car, Ross Chastain appears to be a potential driver for it, as he has expressed interest in continuing with the team part-time after he moves to the Cup Series full-time. On November 4, 2020, it was announced that Rick Ware Racing would be fielding two full-time Xfinity Series teams. The team returned to the series to attempt two races in late 2020 after about a year and a half away, reviving the No. 17 car. Despite this announcement, it was later revealed on February 6, 2021 that RWR would only be fielding the No. 17, which would have an alliance with SS-Green Light Racing, similar to the partnership they had with them for No. 07 car in 2020. On April 6, 2021, RWR announced that the No. 17 driven by Joey Gase would be renumbered to the No. 28 with a Havoline-inspired paint scheme for the Talladega race to honor the late Davey Allison. Gase would also drive the No. 28 (renumbered from the No. 53) at the spring Talladega Cup race. On December 3, 2020, it was revealed that DGM Racing would be fielding a fourth car for the first time, with team owner Mario Gosselin piloting the No. 91 in the season-opener at Daytona for his first Xfinity start as a driver since 2017. The car was also on the entry list the following week at the Daytona Road Course with Preston Pardus, but it was excluded from the field due to lack of owner points with the entry list having over 40 cars, and Pardus replaced Caesar Bacarella in the team's No. 90. It is unclear if the car will attempt additional races later in the season. On December 10, 2020, Richard Childress Racing announced the revival of their No. 2 car, which will be driven full-time by Myatt Snider, who drove for them part-time in 2020. It has yet to be announced if RCR's No. 21 will run part-time in, or not run at all 2021. On December 11, 2020, Our Motorsports announced that they would be expanding to two full-time cars in the Xfinity Series in 2021. The second car will be driven by multiple drivers, beginning with 2018 and 2019 series champion Tyler Reddick at Daytona, Whelen Modified Tour driver Patrick Emerling, ARCA Menards Series West driver Blaine Perkins, and additional drivers that have yet to be announced. Team owner Chris Our confirmed on SiriusXM NASCAR Radio on December 14, 2020 that the number would be the No. 03. After the No. 03 failed to qualify for the races with no practice and qualifying due to owner points with entry lists of over 40 cars, Our Motorsports purchased the points of the No. 23 car from RSS/Reaume Brothers Racing for the remainder of the season starting at Las Vegas in March. On January 19, 2021, Big Machine Records founder Scott Borchetta announced that he and the company were starting a full-time Xfinity Series team, Big Machine Racing, which will field the No. 48 Chevrolet. The team bought cars and equipment from RSS Racing/Reaume Brothers Racing's No. 93 car in 2020.
