Mac Jones Steps Up as Purdy Recovers: Inside the 49ers’ Quarterback Injury Crisis and Denied Controversy

8 Min Read

With Brock Purdy sidelined by a persistent turf toe injury and Mac Jones valiantly playing through knee and oblique issues, the San Francisco 49ers are heading into a critical matchup against the Tampa Bay Buccaneers, steadfastly downplaying any talk of a quarterback controversy even as Jones delivers impressive performances in Purdy’s absence.

The San Francisco 49ers are once again grappling with a significant quarterback challenge as starting signal-caller Brock Purdy remains sidelined by a lingering turf toe injury. This marks Purdy’s second consecutive missed game and his fourth absence in the last five contests. Complicating matters further, backup Mac Jones, who has admirably stepped into the starting role, is battling through his own set of injuries, listed as questionable for Sunday’s pivotal game against the Tampa Bay Buccaneers.

Purdy’s Lingering Turf Toe and the IR Decision

Brock Purdy initially sustained his turf toe injury in the season-opening clash against the Seattle Seahawks. The injury was aggravated during a Week 4 loss to the Jacksonville Jaguars, forcing him off the field. Despite the recurrent nature of the ailment and multiple missed games, San Francisco coach Kyle Shanahan has indicated that the team is not currently considering placing Purdy on injured reserve. This decision suggests optimism for his return later in the season, avoiding a longer absence that an IR designation would entail.

The former “Mr. Irrelevant” quarterback has quickly become a fan favorite, leading the 49ers on an unexpected run last season. His continued absence, however, opens the door for other narratives, particularly given the performance of his understudy.

Mac Jones: A Resurgent Backup Battling Through Adversity

Stepping in for Purdy, Mac Jones has demonstrated remarkable resilience and impressive play. Jones is dealing with injuries to his knee and oblique, both of which he aggravated during the 49ers‘ victory over the Los Angeles Rams on October 2. Despite these physical setbacks, Jones completed 33 of 49 passes for 342 yards and two touchdowns against the Rams. This season, he has accumulated 905 passing yards, six touchdowns, and just one interception on 129 pass attempts.

Jones’s journey to San Francisco marks a significant career revival. After a promising rookie season in New England in 2021, he found himself as a backup in Jacksonville last season. His current stint with the 49ers has been nothing short of spectacular, boasting an undefeated 3-0 record as a starter. He is one of only two quarterbacks in NFL history, alongside Matthew Stafford (2021, Rams), to win his first three starts with a franchise while throwing for at least 900 yards and six touchdowns. His clutch performances include leading game-winning drives against Arizona in Week 3 and the overtime victory against the Rams.

Offensive Coordinator Klay Kubiak lauded Jones’s resilience, stating, “When you see a guy go out there and battle and work through the injuries and get hit and stay in the game when it’s not looking good or when we have to come from behind in a two-minute drill, you learn a lot about a guy. Mac just keeps proving time and time again that he’s made of the right stuff and he’s built to play quarterback in this league.” As per Associated Press reporting, Jones has been limiting his throwing in practice to conserve his arm for game day, a testament to his determination amidst injury.

Addressing the Fabled Quarterback Controversy

Despite Mac Jones‘s impressive run, 49ers General Manager John Lynch has vehemently denied any speculation of a quarterback controversy between Purdy and Jones. Lynch explicitly stated that there is “no tension” between the two quarterbacks and that Purdy is “not worried about Mac Jones taking his job.” This firm stance aims to quash any internal division rumors that could arise from the backup’s success.

Fan discussions, however, often thrive on “what if” scenarios. The narrative of Jones’s undefeated record as a starter contrasting with a hypothetical scenario where Purdy might have struggled (four losses in five starts with eight interceptions, as one article presented to fuel the debate) certainly ignites passionate debate among the faithful. However, as Lynch and the team assert, the focus remains on health and performance, not manufactured drama.

For Jones to truly “take Purdy’s job,” he would likely need to not only continue his stellar play but also for Purdy’s recovery or subsequent performance to falter significantly upon his return. Given Purdy’s previous success and Lynch’s unwavering support, such a scenario remains purely speculative, though the strong play of Jones certainly gives the coaching staff a valuable contingency.

Wider Injury Report for the Buccaneers Game

The 49ers‘ injury woes extend beyond the quarterback position as they prepare to face the Buccaneers. Several key players have been ruled out:

  • Ricky Pearsall (knee) – Unlikely to play.
  • Jordan Watkins (calf)
  • Kevin Gaines (pectoral) – Limited in practice but has a chance to be activated from IR.
  • Yetur Gross-Matos (knee/hamstring)

Additionally, other players are battling injuries and were listed on the recent report, though some returned to practice:

  • Jauan Jennings (rib/ankle) – Returned to practice on a limited basis.
  • Alfred Collins (knee) – Returned to practice on a limited basis.
  • Kalia Davis (hand)
  • Upton Stout (ankle)
  • Malik Mustapha (knee) – No injury designation, on target for season debut after offseason surgery.
  • Robert Beal (ankle) – Did not practice all week and is a candidate to be placed on injured reserve.

With a depleted roster due to injuries, the performance of Mac Jones and the rest of the healthy squad will be crucial as the 49ers navigate this challenging period. The team’s third-string quarterback, Adrian Martinez, who has yet to play in an NFL game, stands ready if further unforeseen circumstances arise, underscoring the precarious nature of the team’s depth.
