Inside linebackers Reuben Foster and Fred Warner were among the many 49ers players who struggled on Sunday in a 39-10 loss to the Los Angeles Rams at Levi’s Stadium.
Foster, in particular, had a rough day. He recorded just one tackle while being responsible for three of the 49ers’ eight missed tackles, according to Pro Football Focus.
Foster, a first-round draft pick in 2017, played 51 of the team’s 61 defensive snaps. He left the game in the fourth quarter after sustaining a right shoulder injury while missing a tackle on a 12-yard touchdown pass he surrendered in coverage against Rams running back Todd Gurley.
