Top-ranked Florida State could be missing three starters when the Seminoles play at Syracuse on Saturday.
Coach Jimbo Fisher announced Monday center Austin Barron is out with an arm injury and will be replaced by redshirt freshman Ryan Hoefeld. Leading receiver Rashad Greene suffered a concussion in last weekend's 43-3 win against Wake Forest and has not been cleared to return. Running back Karlos Williams injured his ankle during the game and is in a walking boot.
Redshirt sophomore Mario Pender would replace Williams if he is unable to play and freshman Dalvin Cook would be the primary backup. Pender and Cook have run for a combined 382 yards and five touchdowns.
Sophomore Jesus "Bobo" Wilson could start in place of Greene, but freshman Travis Rudolph is also a candidate.
