Mason took nine carries for 59 yards and one catch for 13 yards in Friday's 23-12 preseason loss to the 49ers, but he lost a fumble at the goal line on the opening drive.

EDGE Analysis

With Christian McCaffrey and Elijah Mitchell held out, Mason dominated first-team snaps on a night that saw Brock Purdy, Deebo Samuel, Brandon Aiyuk and George Kittle all playing. They faced the Chargers' second-team defense and would've scored 14 points in two drives if not for Mason losing a fumble at the goal line. Tyrion Davis-Price then dominated backfield work with the second-stringers en route to 12 touches for 76 yards, perhaps giving the Niners a tougher decision between him and Mason for the No. 3 RB job. Keeping both isn't out of the question.

Mason rushed five times for 17 yards and failed to bring in his only target in Sunday's 34-7 preseason loss against the Raiders.

EDGE Analysis

Mason struggled to find running lanes mainly due to poor offensive line play, as none of the three San Francisco backs active Sunday sniffed a 4.0 YPC average. It is worth noting that the undrafted standout from last season didn't get a carry until the 49ers' fifth drive, with Tyrion Davis-Price (9-29-0) starting ahead of him sans Christian McCaffrey (rest) and Elijah Mitchell (hip). With neither back performing well, Mason's spot on the roster is likely still secure. Perhaps the lineup swap will motivate the 24-year-old to shake off the rust against the Broncos on Saturday.

Mason has been operating as the 49ers' third running back during offseason activities, Jerry McDonald of The Mercury News reports.

EDGE Analysis

This shouldn't come as a surprise following Mason's strong contributions on special teams and as a backup in 2022. The then-undrafted rookie surpassed third-rounder Tyrion Davis-Price on the depth chart, and it appears he will maintain that position as the young backs battle for spots behind starter Christian McCaffrey in camp.

Mason finished the 2022 season with 43 carries for 258 yards and a touchdown across 16 regular-season games with San Francisco.

EDGE Analysis

Mason was a surprise addition to the active roster out of training camp, and he parlayed that opportunity into a special-teams role to begin the year. The undrafted rookie eventually was called upon to replace injured backups, and he averaged 6.0 yards per carry in his limited action on offense. Mason is signed through the 2024 season, so he figures to operate as the 49ers' third back to open camp behind Christian McCaffrey and Elijah Mitchell (groin).

Mason rushed eight times for 28 yards and wasn't targeted as a receiver in Sunday's 38-13 win over Arizona.

EDGE Analysis

The 49ers welcomed back Elijah Mitchell (knee) from injured reserve, but Mason still received 14 snaps on offense in the regular-season finale. The Georgia Tech product did an admirable job backing up Christian McCaffrey in Mitchell's absence this season, racking up 258 yards on 6.0 yards per carry in limited action over the course of his rookie campaign. Mason will likely see his role limited to special-teams duty in the wild-card round matchup with Seattle this weekend with San Francisco's backfield now at full strength.

Mason (hamstring) rushed two times for 13 yards and a touchdown in Sunday's 37-34 win over Las Vegas.

EDGE Analysis

Mason -- who was limited to special teams due to a hamstring injury last week -- resumed his change-of-pace role behind starter Christian McCaffrey, cashing in one of his two carries for the first touchdown of his career. The undrafted rookie saw significantly-fewer touches than he had previously as San Francisco's No. 2 back, but that was likely the result of head coach Kyle Shanahan leaning on McCaffrey in a tight contest. Assuming his hamstring injury is fully healed, Mason could be in line for a larger workload against the Cardinals on Sunday in a matchup the 49ers should be heavily favored in.

Mason (hamstring) doesn't have an injury designation for Sunday's game against the Raiders, Jennifer Lee Chan of NBC Sports Bay Area reports.

EDGE Analysis

Mason suited up with the hamstring injury last week against Washington but only played special teams while Tyrion Davis-Price operated as the No. 2 running back behind Christian McCaffrey. With Mason now off the injury report, a return to the No. 2 role is possible.

Mason (hamstring) practiced in a limited fashion Thursday, Eric Branch of the San Francisco Chronicle reports.

EDGE Analysis

Mason only managed 17 snaps on special teams this past Saturday versus the Commanders after his hamstring tightened up on him last Wednesday. With back-to-back capped sessions behind him this week, he doesn't appear to be in the clear on the health front just yet, but Friday's injury report could be the bearer of good news for undrafted rookie. If Mason is able to retake the No. 2 RB role behind Christian McCaffrey (knee) on Sunday in Las Vegas, the former would push fellow first-year player Tyrion Davis-Price back down the depth chart.

Mason (hamstring) was limited at Wednesday's practice, Eric Branch of the San Francisco Chronicle reports.

EDGE Analysis

After his hamstring tightened up on him last Wednesday, Mason was limited last Thursday before going down as questionable for Saturday's game against the Commanders. He was active Week 16, but he also was contained to 17 snaps on special teams, as Tyrion Davis-Price handled the RB reps that didn't do to Christian McCaffrey. There's a chance Mason takes over the No. 2 role out of the 49ers backfield Sunday at Las Vegas, but he may have to get back to a full session before the end of Week 17 prep in order to do so.

San Francisco head coach Kyle Shanahan said Monday that Mason is "doing great" in his recovery from a tight hamstring, per David Lombardi of The Athletic.

EDGE Analysis

Mason played in last Saturday's win over Washington but was limited to special teams. Tyrion Davis-Price took over the backup RB role behind Christian McCaffrey in that contest, but Mason is expected to again work behind McCaffrey in Week 17 now that he is showing improvement. Mason had been very effective in his previous three games prior to Saturday, tallying 171 rushing yards on 23 carries.
