Jones did not attempt a pass and lost two yards on two end-of-game kneel-down plays during Sunday's 35-13 victory over the Dolphins.
The 49ers had no trouble building a comfortable lead throughout the contest, leading to Jones coming in to mop up over the final two series. The 28-year-old is coming off a sound 2025 campaign, throwing for 2,151 yards, 13 touchdowns and six interceptions while completing a career-best 69.6 percent of his attempts. While Jones is considered one of the better backup quarterbacks in the NFL, his fantasy ceiling is virtually non-existent as long as Brock Purdy is healthy.
49ers' Mac Jones: Quick appearance in preseason finale
Rotowire
Jones completed one of his five pass attempts for seven yards in Thursday night's preseason finale against the Raiders.
Jones played just eight offensive snaps in the contest, marking a quick end to the preseason for the veteran backup. Despite the poor outing, Jones is still the most likely No. 2 option at quarterback behind starter Brock Purdy. With Kurtis Rourke (ribs) dealing with an injury, Adrian Martinez will likely fill out the QB room as the team heads into Sunday's cutdown day.
Jones (undisclosed) has passed his conditioning test and is cleared for participation in training camp, Vic Tafur and Matt Barrows of The Athletic report.
Jones was able to throw at George Kittle's (Achilles) Tight End University last week. The backup quarterback started eight regular-season games for the 49ers last year and will remain a key depth piece for the organization going into the 2026 season.
