Jones’ Knee Concerns are again in the spotlight as Mac Jones, the San Francisco 49ers’ newly acquired backup quarterback, recently dealt with a knee sprain during the preseason. According to the San Francisco 49ers Official Website, this injury briefly sidelined him, but it’s not expected to significantly impact his role as the primary backup to Brock Purdy for the upcoming season. Jones, 27, has a history of knee issues, but this latest setback appears to be resolved as the regular season approaches.
Mac Jones’ Preseason Knee Sprain
The most recent incident occurred during a preseason game against the Las Vegas Raiders in mid-August 2025. As reported by CBS Sports, Jones sustained a knee sprain in the second quarter after being hit by two defenders while attempting an incomplete pass. Despite grabbing his left leg in pain, he was able to jog off the field and even returned to lead a scoring drive later in the game. However, the injury forced Jones to miss the 49ers’ preseason finale, as noted by NBC Sports.
A History of Knee Injuries
This preseason knee sprain is the latest in Jones’ injury history. While playing for Alabama in college, he suffered a hyperextension of his left knee on November 20, 2020, during a tackle. According to a report from FOX Sports, this led him to miss the remainder of that game, but he returned the following week with minimal long-term effects. Later, in Week 3 of the 2022 NFL season, while with the New England Patriots, Jones sustained a left leg injury against the Baltimore Ravens.

Joining the 49ers
Jones officially joined the San Francisco 49ers on March 14, 2025, signing a two-year deal. His arrival came after stints with the New England Patriots (2021-2023) and the Jacksonville Jaguars (2024). As reported by ClutchPoints, the 49ers had previously considered drafting Jones in 2021 before ultimately selecting Trey Lance.
Impact on the 49ers’ Season
Despite the recent knee sprain, the impact on the 49ers’ season is expected to be minimal. Jones was a full participant in practice on Wednesday, September 3, 2025, indicating that the injury is no longer an issue. Head coach Kyle Shanahan had expressed optimism that Jones would be ready for Week 1, according to FantasyPros. Jones is slated to begin the season as the backup quarterback behind starter Brock Purdy, a role he also held last year with the Jacksonville Jaguars behind Trevor Lawrence. To provide depth during Jones’ brief absence in the preseason, the 49ers re-signed Nate Sudfeld.
The Backup Quarterback Role
Jones’ role as the backup quarterback is crucial for the 49ers’ season. In the event of an injury to Brock Purdy, Jones would be called upon to lead the team. His experience with the Patriots and Jaguars, as detailed on Wikipedia, provides him with valuable knowledge of NFL offenses and game management. The 49ers are hoping that Jones’ knee issues are behind him and that he can provide a reliable option should Purdy be unavailable.
Assessing Jones’ Performance
Evaluating Jones’ performance during his time with the Patriots offers insights into his capabilities. While he showed promise in his rookie season, his performance declined in subsequent years. The 49ers are betting that a change of scenery and a role as a backup will allow Jones to revitalize his career. His ability to quickly learn the 49ers’ offensive system will be key to his success.
