SANTA CLARA, Calif. -- The NFL fined San Francisco 49ers fullback Kyle Juszczyk $14,926 on Thursday for "engaging in offensive demonstrations." According to the league, Juszczyk violated Rule 12, Section 3, Article 1, when he did an "imitation of chugging a beer" with just under eight minutes left in the third quarter of the Niners' win against the Miami Dolphins. Juszczyk immediately pushed back against the fine on social media before holding a brief, three-minute media session at his locker following practice Thursday. Before that began, Juszczyk took the time to place a jug labeled in big letters "Not Beer"...
