WHITE SULPHUR SPRINGS, W. Va. – Running back Raheem Mostert will lose about eight weeks due to “damaged cartilage” in one knee and the injury requires arthroscopic surgery, said Kyle Shanahan, coach of the San Francisco 49ers.
Mostert was put on the disabled list Monday.
Shanahan also confirmed that further examinations of cornerback Jason Verrett’s right knee revealed a torn ACL, an injury that also requires surgery and will end Verrett’s campaign.
Both injuries, combined with a nearly lost 28-point lead over the Detroit Lions in Week 1, affected the 49ers’ spirits after winning their first game of the season at 41-33 and losing Mostert and Verrett. For extended periods after a 2020 season in which the team suffered a cascade of injuries, it left Shanahan with the intention of warning his players not to fall into a “here we go again” attitude.
“It is part of this sport. I’m not going to become everyone’s therapist for this, ”Shanahan noted. “It seems to me that we came out of the game mostly healthy. (The two injuries) were unfortunate situations for them. Hopefully we will have Raheem back later in the year, so we need to make sure (the substitutes) do their job while he’s not with us. “
The backups Shanahan referred to are rookie running backs Elijah Mitchell and Trey Sermon and second-year player JaMycal Hasty.
Mitchell appears to be the one to get the first chance as a starter after setting a 49ers rushing rushing mark (104 for 19 runs) in a debut. Hasty, who ran for a touchdown against Detroit, is expected to rise as second in the rotation with Sermon as third.
For the game against the Lions, it was a surprise that Sermon was inactive after spending most of the preseason as the second running back behind Mostert. Shanahan explained that he was simply outbid, but that the team will look to the third-round draft pick to add depth to the position.
Jeff Wilson Jr., who was Mostert’s primary backup in 2020, is recovering from a meniscus injury sustained in the spring. He is currently on the physically unfit player list, making him eligible to play in 2021 through Week 7.
For his part, Verrett suffered the knee injury with just over seven minutes to play in the game against the Lions. In 2016, he suffered the rupture of the anterior cruciate ligament of the left knee in 2016 and in 2018 of the Achilles tendon.
Shanahan said he spent some time Sunday night with Verrett and that the defender was understandingly upset, particularly after working hard to recover from his previous injuries.
For now, Verrett plans to stay with the team while he entertains at The Greenbrier resort in West Virginia ahead of Sunday’s game against the Philadelphia Eagles.
Shanahan noted that the team is working to get Verrett’s wife to travel to the East Coast to accompany him.
