SANTA CLARA — Defensive tackle Javon Hargrave and linebacker Curtis Robinson officially went on Injured Reserve on Saturday, and the 49ers used one of those roster spots to promote defensive end Sam Okuayinonu from the practice squad.
Defensive tackle Evan Anderson and safety Jaylen Mahoney, a pair of undrafted rookies, were lifted from the practice squad before Sunday’s visit by the New England Patriots.
The 49ers announced no changes to the injury designations for their players Listed Friday as questionable: left tackle Trent Williams (toe), wide receiver Deebo Samuel (calf), safety Talanoa Hufanga (ankle), defensive tackle Jordan Elliott (foot) and linebacker Dee Winters (ankle).
Hargrave suffered a triceps tear Sunday while engaged in a block with two minutes remaining, as the Rams completed a 50-yard pass on a game-tying touchdown drive in their 27-24 comeback. Hargrave signed a lucrative deal in 2023 free agency (four years, $84 million) and made the Pro Bowl after recording seven sacks; he recorded his first sack of the season on Sunday.
Robinson, a fourth-year backup linebacker, tore the ACL in his right knee during Thursday’s punt coverage practice.
Okuayinonu recorded his first career sack last Sunday, when he was lifted from the practice squad for the second time this season; he also played in the opening win over the New York Jets.
The Patriots (1-2) also made a series of moves on Saturday. Alex Austin went on Injured Reserve and sophomore cornerback Isaiah Bolden was promoted from the practice squad. Defensive tackle Trysten Hill and tight end Mitchell Wilcox were also lifted from the practice squad.
