why is mac jones playing today

Mac Jones is playing today because he is starting as the San Francisco 49ers' quarterback in place of the injured Brock Purdy, who is sidelined due to toe soreness. Jones returned from a knee injury and has been praised by coach Kyle Shanahan for his outstanding performance in recent games. Despite battling a sprained knee and forearm cramping, Jones threw for 342 yards and two touchdowns in the latest game, leading the 49ers to an overtime victory against the Los Angeles Rams. His strong play and Purdy's continued injury keep Jones as the starter for the 49ers today.
