The Dolphins have agreed to a deal with former Cowboys OT Marc Colombo, reuniting him with Tony Sparano.

ESPN Dallas' Todd Archer reported that Colombo is expected to be joining Miami. Sparano, the Dolphins' head coach, was the Cowboys' offensive line coach from 2005-2007, overlapping almost three seasons with Colombo.

The Cowboys released Colombo last week. The former first-round pick of the Bears, Colombo started 15 games at right tackle for Dallas last season.

Former Giants C Shaun O'Hara is reportedly visiting with the Dolphins on Monday.

The way we see it

The Dolphins' O-line was not a very effective unit last year, and it didn't help that ORT Vernon Carey ended his season on injured reserve and OLT Jake Long played through a shoulder injury. Long is starting training camp on the physically-unable-to-perform list, and Colombo could compete with Carey to start at right tackle. At the least, he adds much needed depth and experience to the position.
