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.

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.
