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 elevated from the practice squad ahead of 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 sustained a triceps tear Sunday while engaged in a block with two minutes remaining, when 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 upon recording seven sacks; he recorded his first sack this season on Sunday.
Robinson, a fourth-year reserve linebacker, tore the anterior cruciate ligament in his right knee during Thursday’s practice on punt coverage.
Okuayinonu recorded his first career sack last Sunday, when he was elevated from the practice squad for the second time this season; he also played in the season-opening win over the New York Jets.
The Patriots (1-2) also made a series of moves Saturday. Alex Austin went on Injured Reserve and fellow cornerback Isaiah Bolden was promoted from the practice squad. Also, defensive tackle Trysten Hill and tight end Mitchell Wilcox were elevated from the practice squad.
