Coach Urban Meyer said Robinson (heel) will be questionable for Sunday's game against the Bills, Michael DiRocco of ESPN.com reports.
Robinson was unable to practice Wednesday or Thursday but is expected to test things out on the practice field Friday. Meyer indicated it's a pain issue for the 23-year-old, and the tailback could end up being a game-time decision. Carlos Hyde lines up to lead Jacksonville's backfield Sunday should Robinson ultimately be ruled out.
