San Francisco 49ers HC Kyle Shanahan bluntly explained what sparked a postgame scrum that involved WR Jauan Jennings.

Jauan Jennings delivers a mic-drop warning after a dirty Week 12 hit from Panthers' Tre’von Moehrig sparks a brief on-field brawl.

Jennings has had an up-and-down season for the 49ers, missing much of the preseason with a calf injury while he was seeking new contract terms, and later saying he had been playing with broken ribs. He has 37 catches for 419 yards and four touchdowns, including three in the past four weeks.

San Francisco 49ers wide receiver Juan Jennings slapped Carolina Panthers safety Tre'von Moehrig after their 'Monday Night Football' game on Monday, Nov. 24, and later called out Moehrig, explaining his reaction was because of a 'cheap shot' to the groin at the end of the game.
