DAVIE, Fla. — The NFL says Miami Dolphins linebacker Kiko Alonso won't be suspended for his hit that sidelined Baltimore Ravens quarterback Joe Flacco with a concussion.

Flacco was hurt in the Ravens' 40-0 victory Thursday when he slid and was then hit in the head by Alonso, who received a penalty for unnecessary roughness. Alonso said the high hit was unintentional, but angry Ravens players said he should have been ejected for a dirty play .

Miami coach Adam Gase defended Alonso, saying Flacco was trying to run for a first down before he slid.

Flacco missed the rest of the game. Ravens coach John Harbaugh said there's a good chance Flacco will return to play Sunday at Tennessee.

Alonso still faces a possible fine.
