Harper practiced yesterday and is likely to play, although he'll be a gametime decision. Mathis did not practice yesterday, but will also probably play and will be a gametime decision.
There's a light rain in Miami right now. It will be a 50-60% chance of rain the rest of the day leading up to kickoff and a 30-40% chance during the game. Winds will likely be out of the NNE at 13 mph.
