The San Francisco 49ers took on the Jacksonville Jaguars on Sunday for a Week 4 meeting at Levi’s Stadium, and Kyle Shanahan’s team was handed a 26-21 loss, dropping them to 3-1 and into a three-way tie for the top spot in the NFC West.
San Francisco wasn’t the better team on the field throughout the game, as they constantly turned the ball over and continued their embarrassing streak without an interception or a rushing touchdown through the first four weeks. They’ll need to turn things around quick before they take on the 3-1 Los Angeles Rams on Thursday night.
