Fans are unhappy with quarterback Michael Penix Jr.'s performance in Week 7 against the San Francisco 49ers.

This resulted in the Falcons suffering a 20-10 loss at the hands of Kyle Shanahan's team on Sunday.After the game, fans on social media grilled Michael Penix Jr. for his lackluster showcase on the field.
