Lamar Jackson’s drive to win the battle of the famous No. 8s is racing on. Last year, Jackson challenged a trademark claim from Pro Football Hall of Fame quarterback Troy Aikman to put “EIGHT” on apparel and bags.

Jackson, who has worn No. 8 since his college days at Louisville, previously registered the trademark “ERA 8 by Lamar Jackson.” His latest claim argued that Earnhardt’s attempt to trademark that particular version of No. 8 would create confusion among consumers.

Dale Earnhardt Jr. and Lamar Jackson have found themselves in a peculiar legal battle. Dale Jr., of course, became one of the faces of NASCAR while driving the No. 8 car. Jackson has worn that same number throughout his football career and has won two MVPs with it.
