George Kittle's decision to wear and flash a "F--k Dallas" undershirt during Sunday night's 42-10 win over the Cowboys could prove costly.
Adam Schefter of ESPN reports Kittle may be fined for a "personal message' that carries a $10,927 punishment.
Kittle was paying homage to former 49ers linebacker Gary Plummer who wore a similar shirt with the same message during the 1994 season.
Kittle's attire drew the ire of the Cowboys Micah Parsons who chastised Kittle for making things "personal" between the two teams which lead to Deebo Samual to respond saying it "was already personal," between the long time rivals.
