Mostert (knee) is expected to be ready for Week 1, though the Dolphins plan to be cautious with him this offseason, Marcel Louis-Jacques of ESPN.com reports.
In other words, Mostert won't participate in spring practices, which was probably to be expected. He played only nine games over the past two seasons, with his most recent health issue being chipped cartilage in his knee that required October surgery to address. The 30-year-old is part of a rebuilt, veteran backfield that also added Chase Edmonds and Sony Michel this offseason, while Myles Gaskin and Salvon Ahmed are returning players of note. Mostert should compete for carries on early downs once he's healthy.
