San Francisco 49ers quarterback Jimmy Garoppolo was forced to leave the game after a knee injury in their 38-27 loss to the Kansas City Chiefs. Garoppolo completed 20 of 30 passing attempts for 251 yards and two touchdowns.

According to NFL Insider Adam Schefter, Garoppolo injured his left knee. 49ers head coach Kyle Shanahan fears that he may have torn his ACL. The team is grim, but there will be an MRI on Monday to clarify his condition.

There is no telling how severe his injury is for now, but if he is out for an extended period of time, the 49ers will be asking around to find a replacement quarterback soon. Their backup, 2017 third-rounder C.J. Beathard is the only backup option listed on the team's official website. Beathard threw for 1,430 yards and four touchdowns last season, but it's unlikely that he has the skill to go the distance.

Jimmy Garoppolo was made the NFL's highest-paid quarterback when he signed a five-year $137.5 million deal earlier this summer. Since then, Green Bay Packers quarterback Aaron Rodgers has surpassed that mark. Regardless, the 49ers invested in Garopollo long term.

Former 49ers quarterback Colin Kaepernick is actively working out and still looking for a job in the NFL. The team doesn't have a lot of options so that a reunion could be on the way. Multiple teams showed interest in Baltimore Ravens quarterback Robert Griffin III after his promising preseason performance with his new team.

There is no need to panic now, as Garoppolo will still need to be evaluated before any serious moves are made. However, the 49ers are now 1-2. Injuries to starting running back Jerrick McKinnon and wide receiver Marquise Goodwin hurt the team early on, but this hit would inflict a next level blow to their success this season.
