The initial prognosis had Mostert missing about eight weeks, providing hope that the veteran running back would return this season. It wasn't long before Mostert announced that he opted for surgery, ending his 2021 campaign.
"After consulting with multiple doctors and weighing my options, I will be having season-ending surgery to repair my knee," wrote Mostert via his announcement.
Mostert underwent surgery this past week and posted the following post-surgery video via Instagram.
Today, Mostert thanked the fans who wished him well and expressed his excitement as he embarks on the road to recovery.
Added Mostert in his initial announcement: "I wish more than anything I could be out there on the field with my brothers!!! Thank you for your support in our decision. I'M FAR FROM DONE!"
Next season will be Mostert's eighth in the NFL. During his time with San Francisco, he has amassed 1,610 rushing yards, 361 receiving yards, 11 rushing touchdowns, and three receiving touchdowns through 46 games and nine starts.
Mostert waited a month for his surgery. The running back was seen on the sidelines with his teammates following the injury.
"He's still waiting to have the surgery," head coach Kyle Shanahan explained earlier this month, "which they told me it takes some time for them to find the right donor for that part. So, he's just waiting and spending time with the team."
In April, the 49ers drafted two running backs — Trey Sermon out of Ohio State in the third round and Elijah Mitchell out of Louisiana in the sixth round.
