Bostic received a surprise of his own Wednesday morning.
A replay of the tackle shows some helmet-to-helmet contact, but Bostic wraps his arms and delivers a tackle that officials didn't flag. The league clearly believes the play warranted a penalty.
"Bostic's going to square you up, form tackle you and make you remember," ESPN's Trent Dilfer remarked.
The league has yet to confirm the fine, but if it sticks, it represents more than 5 percent of Bostic's $405,000 base salary.
