The shine on Quinton Patton’s career day against New Orleans dimmed Friday.

The 49ers receiver was fined $18,231 for a horse-collar tackle on linebacker Craig Robertson following an interception of Colin Kaepernick in the first quarter of Sunday’s loss, according to CSN Bay Area.

Patton was flagged for the tackle, giving the Saints the ball at the 49ers’ 12-yard line, before making it 14-3 five plays later near the end of the first quarter. Drew Brees found rookie receiver Michael Thomas for his first of two touchdown receptions on the day.

Patton posted career highs in catches (six) and yardage (106) while Kaepernick threw for 398 yards, the second most of his six-year career.

But the Saints gave San Francisco its seventh-straight loss, 41-23, while after the home team had four turnovers and went 0-for-2 in the red zone.
