NFL Network’s Ian Rapoport reports Isiah Pacheco (back) could return in early December.

According to Rapoport, Pacheco “had surgery to remove a body that was pressing on a nerve in his back.” The 27-year-old back is looking at a 12-week recovery, but if all goes well, he could return for the final month of the season. If the Lions don’t add anybody to their backfield in the coming days/weeks, Sione Vaki and Jacob Saylors will continue to serve as the primary backups behind Jahmyr Gibbs.
