According to one published report, the Dolphins also agreed to terms with offensive tackle Damion McIntosh, who already had agreed to a deal last weekend before it was discovered he had flunked his physical because of an ankle injury that required surgery.
Finally, it looks like offensive tackle Spencer Folau, who started for the Dolphins in 2001, could return to Miami after spending the last two seasons with New Orleans.
Folau is due in for a visit on Friday.
As for the David Boston situation, the Dolphins are said to be the front-runners for his services because Boston really wants to be reunited with receivers coach Jerry Sullivan.
The Dolphins reportedly have spoken to Boston. The two issues left to clear are working a new contract with Boston and agreeing on compensation with the Chargers, who would like a third-round pick for Boston but might wind up settling for less.
