Robert Jones Injury: Likely out 2-3 months

Jones suffered a broken bone in his neck at practice Sunday and might miss 2-3 months, Adam Schefter of ESPN reports.

The offensive guard had been playing with the first team during training camp so far, per Schefter. Jones started all 17 games at left guard for the Dolphins last year before signing a one-year deal with the Cowboys in the offseason. Tyler Smith could be the next man up at left guard.
