The injury took place with 5:35 left in a 38-27 loss to the Chiefs, as Garoppolo gained 13 yards on a run but finished the run by colliding with Chiefs cornerback Steven Nelson. The 26-year-old went down and was immediately taken out, as he finished the game completing 20-of-30 passes for 251 yards and two touchdowns. He had no interceptions in the game and finished with a quarterback rating of 114.7.
49ers head coach Kyle Shannahan says that backup C.J. Beathard will take over as the starter. Beathard did start five games as a rookie last season and led the team to their first win of the season against the New York Giants. In seven NFL games, the new starter has completed 54.9 percent of his passes for 1,430 yards, four touchdowns, and six interceptions. He is taking over for a $137 million quarterback, which adds to the pressure for the deflated 49ers team, which is off to a 1-2 start to their season.
The 49ers also took a hit on the defensive side of the ball, as cornerback Richard Sherman will miss two-three weeks with a calf strain. Coach Shanahan announced the news after Sunday's loss, saying the defensive star would miss "a couple weeks." The injury occurred in the second quarter in Kansas City, but the exact cause of the injury is unknown. Sherman did miss some practice time leading in to Sunday's game with a heel/calf issue, so this could've been a reaction to that same injury.
Meanwhile, one of the top teams in football took a couple hits on defense starting with cornerback Marcus Peters, who suffered a calf injury during the Los Angeles Rams' win over the Los Angeles Chargers on Sunday. Peters suffered the injury in the second quarter and did not return. He was seen walking out of the locker room after the game with a walking boot on his right foot. There is no official timetable for his return, but he will be out for Thursday's game against the Minnesota Vikings.
The other defensive star to go down for the Rams was cornerback Aqib Talib, who will miss about a month with a high ankle sprain. The injury also took place on Sunday, but this one in the second half, as he left the locker room after the game on a crutch, wearing a walking boot on his left foot. The former Denver Broncos cornerback, who came over in the off-season, has seven tackles and two pass deflections in his first season with the undefeated Rams.
