DeAndre Hopkins was clearly angry after an offensive pass interference call early in the second half of the season finale in Los Angeles last week, a call that wiped out a 42-yard reception down to the L.A. 8-yard line with the Cards trailing, 15-7.

He was angry enough that he argued the call vociferously, and then punctuated it with a single-digit salute that drew a flag and, what we found out Saturday, also earned Hopkins a $28,075 fine. That's the first-offense cost for "Verbal or other Non-Physical Offense Against Official."

According to spotrac.com, Hopkins was the only Cardinal to be fined for an infraction this season.

The Cards lost the game, 18-7.

It was a frustrating finish to the season for Hopkins -- who was a second-team All-Pro with 115 catches, 1,407 yards and six touchdowns -- and the Cardinals. With Kyler Murray out most of the game with an ankle injury, the offense went nowhere (Chris Streveler threw the 42-yard pass, which would have been a big deal, although on replay it did look like Hopkins grabbed and threw out of the way defensive back John Johnson.) Hopkins had four catches for 35 yards in the last game.
