DAVIE, Fla. (AP) Miami Dolphins tight ends Dion Sims and Jordan Cameron have been ruled out of Sunday's game against the Jets because both are still in the concussion protocol.
Cameron has missed the past four games, and Sims has missed one game.
Cornerback Xavien Howard was also ruled out, as expected, because of a knee injury.
