49ers update: It’s wait-and-see on Mason, Pearsall to practice, and they may need another new kicker

The NFL’s leading rusher in 2023 remains out indefinitely, with Christian McCaffery nursing Achilles tendinitis in both legs.

As for the NFL’s leading rusher in 2024, Jordan Mason has a sprained AC joint in his left shoulder so it’s not a serious injury but 49ers coach Kyle Shanahan stopped short of saying he would be ready to play against the Kansas City Chiefs on Oct. 20 at Levi’s Stadium.

McCaffrey, who had 1,459 yards last season, is on injured reserve and will not practice next week although Shanahan said he is “continuing to improve.” Mason’s availability will be sorted out after three days off and a week of practice.

“We take it as good news, but that doesn’t guarantee he’ll be ready to play,” Shanahan said Friday in his weekly day-after call with local writers. “It was positive that it wasn’t worse than that.”

Mason had 73 yards on nine carries in a 36-24 win over the Seahawks Thursday night, giving him 609 yards on 114 carries through six games. Going into Sunday’s games, that leads the NFL in rushing although Derrick Henry of Baltimore is close behind with 572. He was injured with 9:38 left in the half when he landed heavily on his shoulder after a 14-yard gain when hit by safety Julian Love.

Mason left the game but returned in the second half with his left shoulder taped and gained eight yards on the first carry of the third quarter. He was moving awkwardly after the carry, however, left the game and did not return.

In Mason’s absence, rookie Isaac Guerendo and Patrick Taylor Jr. came on and the 49ers finished with 228 yards rushing, including a 76-yard burst by Guerendo when the 49ers put the game away.

“I thought both did a really good job,” Shanahan said. “We really didn’t miss a beat with it. They hit the right holes, ran hard, they were prepared and didn’t hesitate when they got their opportunities.”

While McCaffrey isn’t ready to practice, Shanahan said the 49ers expect to open the 21-day practice window for first-round draft pick Ricky Pearsall Jr., who had been on the non-football injury list since being shot in the chest during a robbery attempt on Aug. 31.

It’s unlikely Pearsall would be activated for the Chiefs game.

“Most likely I think it would be a longer ramp-up period,” Shanahan said. “Healthwise he’s totally good to go. But I really won’t decide until I watch him practice. We’re not going to rush it or anything. If he’s ready he’s ready and if not we’ve got a few weeks.”

The 49ers could also be in the market for another place kicker as Matthew Wright had a dislocated shoulder while attempting to make a tackle on a 37-yard kickoff return by Dee Williams. Shanahan said the shoulder was popped into place, but that an MRI would reveal the extent of the damage.

Wright won the job in a tryout with three other kickers last week when Jake Moody was lost to a high ankle sprain — also while making a tackle on a kickoff return. He was 3-for-3 on field goal attempts against Seattle.

Rookie safety Malik Mustapha, who opened Thursday’s game with an interception before suffering an ankle sprain, is day-to-day, Shanahan said Friday.

Shanahan said cornerback Charvarius Ward (knee) and defensive tackle Jordan Elliott (knee), who were inactive against Seattle, were day-to-day. It is hoped that linebacker Demetrius Flannigan-Fowles (calf) will begin practicing this week.

SNAP JUDGEMENTS

65: Right guard Colton McKivitz and center Jake Brendel were among four who played every offensive snap (Puni and Purdy were the others. Both take their share of heat, but they opened the hole that saw Guerendo burst for 76 yards to put the game on ice as well as on Kyle Juszczyk’s 6-yard run.

62: Brandon Aiyuk played nine more snaps than Samuel and was targeted four times by Purdy with two receptions for 37 yards. His presence drew coverage that enabled Samuel to be alone for a 76-yard touchdown.

59: Maliek Collins, in part because Jordan Elliott (knee) was inactive, played 59 snaps — the most since he had 60 in Week 3 of the 2018 season for Dallas. He had just one tackle and one quarterback hit but was conspicuous for penetrating the middle of the Seattle offensive line.

58: George Odum, who opened the season as a starter, was forced into action with Talanoa Hufanga on IR and Mustapha injured after 20 snaps. Had six tackles, broke up a pass at the goal line, had an additional pass defensed and also carried a special teams load with 20 additional snaps.

51: Aaron Banks had cramping at left guard, giving way to Spencer Burford a former starter who had just one snap in his previous four games.

16: Running back Patrick Taylor got his first five carries as a 49er (gaining 16 yards), caught one pass for 12 yards and returned two kickoffs for 45 yards.

14: Place kicker Matthew Wright’s final special teams snap came attempting to tackle Dee Williams on a 37-yard kickoff return with the game decided. Ouch.
