SANTA CLARA, Calif. -- Friday provided closure perhaps for Colin Kaepernick's most forgettable NFL Sunday.The NFL said it fined the San Francisco 49ers' quarterback $7,875 for grabbing the facemask of his opponent in a 10-9 loss to Carolina on Sunday.Such a penalty (and a fine) is a rarity for a quarterback. Kaepernick and his coach, Jim Harbaugh, fruitlessly argued for Kaepernick not to be penalized on the play.It added to a miserable day for Kaepernick.
