Mason finished the 2022 season with 43 carries for 258 yards and a touchdown across 16 games with San Francisco.
What it means:
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 was eventually 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 was not targeted as a receiver in Sunday's 38-13 win over Arizona.
What it means:
The 49ers welcomed back Elijah Mitchell (knee) from injured reserve, but Mason still received 14 snaps on offense (23 percent). 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 his rookie campaign. Mason will likely see his role limited to special teams in the wild-card round with San Francisco's backfield -- including Deebo Samuel -- back at full strength ahead of Saturday's playoff matchup against Seattle.
Mason (hamstring) rushed two times for 13 yards and a touchdown in Sunday's 37-34 win over Las Vegas.
What it means:
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.
What it means:
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.
What it means:
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.
What it means:
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.
