ORLANDO, Fla. — Running back Arian Foster had a 2-yard touchdown run in the Miami Dolphins’ 17-6 win over the Atlanta Falcons on Thursday night. Foster, who joined the Dolphins during the offseason and is coming off an Achilles injury, had his most extensive playing time with his new team in the third preseason game that was played at Orlando’s Camping World Stadium. “It’s just a testament to the work we have been putting in, it is doing the work every single day,” Foster said.
