Buffalo Bills offensive guard John Miller departed Sunday’s game in the second half with an oblique strain, according to Bills head coach Sean McDermott at his usual Monday press conference. The severity of the injury is still being evaluated, making Miller an early question mark for next Sunday’s battle with the Miami Dolphins. Interior backup Ryan Groy played in Miller’s place, with Vlad Ducasse inactive for the first time this season. If Miller can’t go, the Bills will need to decide whether to activate Ducasse or rookie Ike Boettger, who’s spent the whole season as an inactive member of the roster.
