Mostert (knee) didn't participate in Thursday's practice, Jennifer Lee Chan of NBC Sports Bay Area reports.

Mostert wasn't in attendance for the 49ers' second practice in a row, with Matt Barrows of The Athletic relaying that the running back left the team and headed to Cleveland to witness the birth of his second child. The 49ers may not even ask Mostert to return to the East Coast before Sunday's game against the Giants, as the running back wasn't expected to be available for the contest anyway after suffering a sprained MCL during the Week 2 win over the Jets. The injury isn't believed to be a major concern, as Mostert could be a candidate to play Week 4 against Philadelphia if he's able to get back on the practice field in some capacity. At least for the Week 3 matchup, however, the 49ers will likely lean on Jerick McKinnon and Jeff Wilson to handle most of the reps out of the backfield.

Perine (ankle) was a limited participant in Thursday's practice, Ralph Vacchiano of SportsNet New York reports.

Despite having his reps capped in both of the Jets' first two practices of the week, Perine is still believed to be on track to play Sunday against the Colts. If Perine is active this weekend, coach Adam Gase hinted Thursday that the rookie could be more involved after he carried three times for 17 yards while playing nine offensive snaps in last week's loss to the 49ers, according to Manish Mehta of the New York Daily News. Frank Gore still projects to serve as the Jets' lead option on the ground, though he may cede some touches to Perine and/or Kalen Ballage (ribs) after carrying 21 times against San Francisco.

Jacobs (hip) wasn't spotted at the start of Thursday's practice, Paul Gutierrez of ESPN.com reports.

We'll have to see if the running back officially ends up listed as limited or as a non-participant Thursday. If he does go down as a non-participant for the second day in a row, then what Jacobs is able to do on the field Friday will be telling with regard to his status for Sunday's game against the Patriots.

Moss (toe) isn't on the field for Thursday's practice, Chris Brown of the Bills' official site reports.

He'll go down as a non-participant for the second day in a row, leaving his status uncertain for Sunday's game against the Rams. Before determining whether he'll carry a designation into the Week 3 contest, the Bills will see what Moss can do during their final practice session Friday. If Moss ends up missing the first game of his career, starting running back Devin Singletary -- who hasn't played more than 60 percent of the offensive snaps in either of the Bills' first two contests -- will likely be headed for a bigger workload.

Walter has inked a deal with the 49ers' practice squad.

Walter came into the league with San Francisco after he was undrafted in the 2019 draft. He's spent time with the Giants as well as in the XFL with Dallas the past two years, and he has just one game of NFL experience.

Jacobs (hip) was listed as a non-participant on the Raiders' estimated practice report released Wednesday.

The Raiders' initial injury report of the week is lengthy, but that's not a big surprise with the team having played two days earlier. Star tight end Darren Waller (knee) was also listed as a non-participant Wednesday, but the expectation is that both he and Jacobs will be able to practice in some capacity Thursday.

Clement did not practice Wednesday due to an illness.

Clement should suit up against the Bengals on Sunday as long as he's able to shake his illness before the contest. The 25-year-old didn't see any touches Week 2 with Miles Sanders back in the lineup, so Clement's status won't carry much of a fantasy impact one way or another.

Boone (concussion) didn't practice Wednesday.

Boone entered the league's concussion protocol during this past Sunday's loss to the Colts. He has two more practices to get on the field ahead of Week 3's matchup versus the Titans; otherwise, he'll likely miss his first game since 2018. Since he's played exclusively on special teams this season, his injury isn't a concern for the offensive dynamic.

Perine (ankle) was a limited participant in Wednesday's practice, Andrew Walker of the Colts' official site reports.

Perine still appears to be bothered by the ankle injury that pushed his NFL debut back a week, though he looked spry in limited action with 17 yards on three carries in Sunday's loss to the 49ers. If Perine can play through the injury once more against the Colts in Week 3, he could earn more touches in a backfield currently headlined by Frank Gore, with Le'Veon Bell (hamstring) on injured reserve.

Evans (hamstring) was a full participant in Wednesday's practice, Jim Wyatt of the Titans' official site reports.

Evans missed Tennessee's first two games, but he's poised to finally make his NFL debut Sunday against the Vikings. The rookie third-rounder should serve in a change-of-pace role behind workhorse running back Derrick Henry.
