The Miami Dolphins move into their fourth day of training camp on Monday, meaning the team will be able to break out the pads for the first time this season. Sunday’s practice featured the first time running back Arian Foster was able to practice with the club, having been activated from the Physically Unable to Perform list earlier in the morning. Foster, who is coming back from a torn Achilles tear he suffered last year as a member of the Houston Texans in a game against the Dolphins, signed with the Dolphins in early July, providing the team with veteran depth in a young running back corps.
