49ers' Marques Sigle: Won't play Sunday
Sigle (ankle) has been ruled out ahead of Sunday's game against the Falcons.
Sigle managed to upgrade to a limited participant in Friday's practice after missing consecutive sessions to start Week 7 prep. The strong safety's last-minute upgrade in participation level was not enough to enable him to suit up for Sunday's game, leaving Malik Mustapha as a starter in the 49ers' secondary for a third consecutive week.

49ers' Marques Sigle: DNP Wednesday
Sigle (ankle) did not participate in Wednesday's practice, Harrison Rich of the San Francisco Chronicle reports.
Sigle has not practiced since being diagnosed as week-to-week with the high-ankle sprain he sustained in the 49ers' Week 4 win over the Broncos. Wednesday's injury report signals that Malik Mustapha is once again taking first-team reps at strong safety in Sigle's place in anticipation of the team's Week 7 game against the Falcons.

49ers' Marques Sigle: Deemed out for Monday Night Football
Sigle (ankle) won't play in Monday's Week 6 matchup against Washington, Cam Inman of The San Jose Mercury News reports.
Sigle is dealing with a high-ankle sprain that he suffered Week 4 versus Denver. The second-year safety missed this past Sunday's win over Seattle and is now set to sit out a second straight game. In Sigle's absence, Malik Mustapha will likely draw another start.

49ers' Marques Sigle: No practice Thursday
Sigle (ankle) didn't take part in Thursday's practice, Matt Barrows of The Athletic reports.
After Sigle suffered a high-ankle sprain in Week 4, head coach Kyle Shanahan said that the second-year pro was slated to miss multiple weeks. With one absence under his belt so far and no practice reps to begin Week 6 prep, he appears to be trending toward another DNP on Monday versus the Commanders. The 49ers can confirm as much when they post their final injury report of the week Saturday.

49ers' Marques Sigle: Set to miss multiple weeks
Sigle is expected to miss multiple weeks due to a high-ankle injury that he sustained during the 49ers' 24-14 win over the Broncos on Sunday, Matt Barrows of The Athletic reports.
Sigle sustained the injury late in the first quarter while on kickoff coverage and was not on the field for the 49ers' final defensive drive of the game. It wouldn't be surprising if the second-year pro goes on injured reserve, and in his absence, Malik Mustapha figures to be the next man up at safety next to Ji'Ayir Brown, with Siran Neal and Ashtyn Davis both providing depth at the position.

49ers' Marques Sigle: Dealing with ankle injury
Sigle suffered an ankle injury during Sunday's 24-14 win over the Broncos.

49ers' Marques Sigle: Gets first career sack Sunday
Sigle recorded seven tackles (three solo), including 1.0 sacks, during Sunday's 35-13 win versus the Dolphins.
Sigle followed up a strong performance in Week 1 with another good game in Week 2, and he has now logged six-plus tackles in all of his last four games going back to last postseason. He has probably played himself into IDP consideration in some formats going into a Week 3 matchup versus the Cardinals.

49ers' Marques Sigle: Racks up nine tackles in win
Sigle recorded nine tackles (four solo) during the 49ers' 27-7 win against the Rams in Week 1.
Sigle was on the field for all 61 of San Francisco's defensive snaps in Week 1, and his tackle total was the second best on the team behind Fred Warner's 11. He may be a worthwhile IDP consideration in some leagues heading into a Week 2 matchup versus the Giants.

49ers' Marques Sigle: Practices Saturday
Sigle (oblique) was a full participant in Saturday's practice, Matt Maiocco of NBC Sports Bay Area reports.
Sigle suffered an oblique injury during last Thursday's preseason contest against the Titans. The strong safety's full participation in Saturday's session implies he has moved past the issue and will be ready for next Thursday's preseason game against the Chargers. Sigle logged two tackles (one solo) against the Titans before finishing his night due to the oblique issue.

49ers' Marques Sigle: Fills in for injured starter
Sigle finished the 2025 regular season with 52 tackles (28 solo) and two passes defended across 15 games with the 49ers.
The fifth-round rookie began his pro career by making five starts in place of injured safety Malik Mustapha. Sigle accrued 39 of his 52 tackles during that span, showing flashes of IDP utility. The 23-year-old figures to serve as depth behind Mustapha and Ji'Ayir Brown in 2026, especially with Jason Pinnock set to become an unrestricted free agent this offseason.

49ers' Marques Sigle: Healthy scratch Sunday
Sigle (coach's decision) is inactive for Sunday's game against the Giants, Briana Jeannel of the 49ers' official site reports.
The safety started the first seven games of the season and played on every defensive snap from Week 1 to Week 5, but he saw his playing time drop from 62 percent of the defensive snaps to 31 percent to zero over the last three weeks, following the return of Malik Mustapha (knee) from injured reserve. Jason Pinnock is serving as San Francisco's third safety behind Mustapha and Ji'Ayir Brown.

49ers' Marques Sigle: Sees playing time drop in Week 7
Sigle recorded two tackles (one solo) while playing just 31 percent of San Francisco's defensive snaps in Sunday's 20-10 win over Atlanta.
Sigle played every one of San Francisco's defensive snaps from Week 1 to Week 5, but he dipped to a 62 percent share upon the return of Malik Mustapha from IR in Week 6 versus Tampa Bay. The rookie safety's defensive snap share then dropped to 31 percent Sunday, with Mustapha at 69 percent and Jason Pinnock at 35 percent. David Lombardi of SFStandard.com suggests that Mustapha will ultimately be a regular starter while Sigle, Pinnock and Ji'Ayir Brown -- who played every defensive snap Sunday -- contend for the No. 2 spot.

49ers' Marques Sigle: Team-high 13 tackles in Week 5 win
Sigle registered 13 tackles (seven solo) and one pass defense during Thursday's 26-23 overtime win over the Rams.
Sigle reached double-digit tackles for the first time this season, and he finished Thursday's game with the second most tackles behind Rams linebacker Nate Landman (14). Sigle has played every defensive snap in each of the first five games of the regular season and is up to 39 tackles (22 solo), two pass defenses and one forced fumble. His playing time could take a dip with Malik Mustapha (knee) close to returning from the reserve/PUP list.
