Quarterback Mac Jones, already serving in relief duty for the injured Brock Purdy, told reporters after Sunday's 16-15 win over the Arizona Cardinals that he reaggravated the same PCL sprain that hampered him during training camp.

Purdy has missed two games with a turf toe injury, but Jones is 2-0 as a starter. On Sunday, Jones aggravated the knee sprain he suffered in training camp, playing with and without a bulky knee brace during a 16-15 comeback win over the Cardinals.

We break down the fantasy football outlook of Mac Jones ahead of the 49ers’ Week 3 matchup against the Cardinals.

Mac Jones told reporters after Sunday's win over the Cardinals that he aggravated a PCL sprain that he initially suffered this summer. Jones was clearly affected by the injury during the game, but he remained in for the entire contest.

Carson Wentz and Marcus Mariota were sharp in leading their teams to lopsided wins as fill-in starters. Mac Jones overcame a costly turnover and engineered a game-winning final drive.

Jones threw an interception with the game tied in the fourth quarter against the Cardinals when he fired a pass downfield to Ricky Pearsall that was picked off by Dadrion Taylor-Demerson. A few minutes later San Francisco took a safety to fall behind, but Jones was able to lead a game-winning drive in the final minutes.

They needed every last second to get it done, but thanks to a game-winning field goal from kicker Eddy Pineiro as time ran out, the San Francisco 49ers moved to 3-0 on Sunday with a 16-15 win over the Arizona Cardinals in their home opener at Levi's Stadium in Santa...

With all the injuries they've had to deal with, the San Francisco 49ers have plenty of excuses not to win games.
