Pro Football Rumors
While 49ers backup quarterback Mac Jones continued a resurgent 2025 in a 34-24 win over the Giants in Week 9, he will not play his way into the team’s starting job. Head coach Kyle Shanahan made it clear on Monday that Jones will return to a No. 2 role when starter Brock Purdy is ready to come back from a toe injury.
Asked if Jones’ play has allowed the 49ers to be more cautious with Purdy, Shanahan said (via Matt Barrows of The Athletic): “They’re not related. This is Brock’s team. When Brock’s good to go and everything and can play like Brock, there’s no decision to be made.”
After going 15th overall to the Patriots in the 2021 draft, Jones finished second in Offensive Rookie of the Year voting and helped the Pats to a playoff berth. The Alabama product was unable to replicate his first-season output with the Patriots or the Jaguars from 2022-24, though, leading him to ink a two-year, $7MM contract with the 49ers last offseason.
Jones reportedly turned down richer offers to function as Purdy’s backup, but choosing San Francisco has worked out well for him and the team. With Purdy having missed seven of the 49ers’ nine games, including five in a row, Jones has led the 6-3 club to a 5-2 record in his starts. The 27-year-old has completed 67.2% of passes for 1,832 yards, 10 touchdowns, and five interceptions in the process. He ranks a solid 15th in the league in QBR.
After picking up his fourth win in Week 7, Jones earned $400K in incentives, per Tom Pelissero of NFL Network. He collected another $100K for the 49ers’ Week 9 victory, which will continue to be the case as long as he plays at least 25% of offensive snaps, according to Dan Graziano of ESPN. Jones will rake in another $550K if he plays 50% of offensive snaps this season and the 49ers earn a playoff berth.
It’s unclear whether Purdy will play this Sunday against the NFC West rival Rams (6-2), who lost at home to Jones and the 49ers in Week 5. Regardless, it’s unsurprising that Shanahan is continuing to back Purdy, one of the team’s greatest individual success stories during his eight-plus years as the head coach.
Purdy quickly went from Mr. Irrelevant – the last overall pick in the 2022 draft – to establishing himself as a high-end starter. The 49ers went 17-4 with Purdy at the helm through the 2023 regular season, which ended with an overtime loss to the Chiefs in Super Bowl LVIII.
San Francisco failed to make the playoffs during an injury-plagued 2024 in which Purdy’s numbers declined. However, that didn’t stop the 49ers from signing the 25-year-old to a mammoth extension last May. Just months removed from securing a five-year, $265MM deal that includes $181MM in guarantees, Purdy is in no danger of a demotion to clipboard-holding duties. The only question is when he’ll be healthy enough to start again.
