San Francisco 49ers starting quarterback Brock Purdy was asked how the practice week has gone for him, having to deal with a toe injury: “It’s been good. Really like where I’m at with the progress. Healing up. Feeling better and dropping back, throwing. I like where I’m at. It’s been good.”

While the San Francisco 49ers were attempting to win the game against the Arizona Cardinals, Mac Jones had to rely on Christian McCaffrey for help.

The San Francisco 49ers are undefeated through three weeks despite starting quarterback Brock Purdy missing two games due to a turf toe injury. Backup Mac Jones playing well in his absence is a win-win for the organization.

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.

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.

Now in his third act as an NFL quarterback, Jones has already had two opportunities to prove that he has good football left in him. In the process, the 49ers have learned a lot about their No. 2 signal-caller, even as Brock Purdy is poised to return from a toe injury sooner than later.

Mac Jones continues winning the trust and belief of his 49ers teammates after San Francisco's thrilling Week 3 victory over the Arizona Cardinals.

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.

With Jauan Jennings missing from the lineup, Jones targeted either Christian McCaffrey or Ricky Pearsall on 26 of his 38 pass attempts.

Mac Jones wins again, Jabrill Peppers gets his revenge, and more on notable former Patriots around the league.
