Malik Mustapha, not Marques Sigle, lines up at safety alongside Ji'Ayir Brown with the 49ers' first-team defense on the opening defensive snap against the Los Angeles Rams on September 10, 2026. If Sigle is on the field with the first team on that snap and Mustapha is not, this call is wrong.
None of the three defensive backs San Francisco worked out on August 14, 2026, Bryce Hall, Troy Pride Jr. and Corey Mayfield Jr., signs with the 49ers on or before August 20, 2026. The take is CORRECT if the club's transaction log carries no signing of any of the three by the end of August 20. It is WRONG if any one of them is signed in that window, whatever the corresponding move is.
Jack Jones, No. 25, and Marques Sigle, No. 36, were in uniform for Saturday's 11:50 a.m. practice, two days after leaving the preseason opener with a hand and an oblique. Jacob Cowing, No. 6, was too. Christian McCaffrey (tightness), Nick Bosa (soreness and tendinitis in the surgically repaired knee) and Kurtis Rourke (ribs) did not practise. No transaction has been announced since August 12 on the club's own log and August 13 on ESPN's, and the roster sits at 90 chargeable players against a limit of 90, counted table by table on Saturday afternoon. Thursday's running backs carried 23 times for 52 yards. Nothing on the 53-man projection crossed the cut line.

The 49ers worked out three defensive backs on Friday, per David Bonilla off the NFL's daily transaction report, with Nate Hobbs out a few weeks, Jack Jones nursing a hand and Marques Sigle an oblique. Bryce Hall and Corey Mayfield Jr. were teammates on the UFL champion Louisville Kings, and Troy Pride Jr. was a fourth-round pick in the same 2020 draft that took Hall in the fifth. No signing had been announced by mid-afternoon, and the roster has been full for ten days. Kurtis Rourke was released from the hospital Thursday night and no result of his further imaging has been published. The first snap counts of the preseason put Robert Jones and Connor Colby on opposite sides of the centre for all 44 first-unit snaps, and Jordan Watkins on the field for 58 while Jacob Cowing took none.

Camp Battles, second installment. Nick Wagoner has Ji'Ayir Brown taking all the first-team free safety reps in a contract year, which is not what the preview said would happen. The live competition is beside him, between an incumbent with 22 starts and a fifth-round second-year player, and it has been contested for exactly one practice because Malik Mustapha strained a hamstring on Monday. Everything on the record was recorded in shorts. The pads arrive Friday.
