The clock is ticking on Willis McGahee.
The Denver Broncos' running back injured his left hamstring last week against the Kansas City Chiefs and was limited in his second straight practice Wednesday morning, according to The Denver Post, leaving his availability in question for Thursday night's game against the New York Jets.
The Broncos listed McGahee as questionable on their final injury report Wednesday.
With Knowshon Moreno placed on injured reserve this week, Lance Ball -- previously the team's third-string back -- would make his first career start if McGahee can't go.
