Walton (thumb) was a limited participant in Thursday's practice, Armando Salguero of the Miami Herald reports.
Walton has opened the week with two straight limited practice sessions, but there doesn't seem to be much concern about his availability for Sunday's game against the Bills. In fact, coach Brian Flores indicated that he "could see" Walton serving as the Dolphins' lead option on the ground in the contest, per Hal Habib of The Palm Beach Post, though Kenyan Drake is still expected to see his fair share of involvement as well. Even so, with Drake on the trade market and a candidate to be dealt before the Oct. 29 deadline, Walton could be in line for significant opportunities moving forward if he continues to impress the Dolphins staff, according to Barry Jackson of the Miami Herald.
