Carter was diagnosed Monday with a low-grade high-ankle sprain that will likely keep him sidelined for 2-to-3 weeks, Adam Schefter of ESPN reports.
Schefter's report indicates that Carter is dealing with either a Grade 1 or Grade 2 sprain after the running back was forced out of Sunday's 24-17 loss to the Dolphins with the injury. After the rookie running back exited the contest early in the third quarter, Tevin Coleman out-touched Ty Johnson by a 4-2 margin. Expect Coleman and Johnson to work in a loose timeshare while Carter is likely out for at least the next two games, with La'Mical Perine -- who was inactive Week 11 -- ranking third in the backfield pecking order.
