The team released Ryan on Thursday.
To take his spot on the roster, the Dolphins signed T Kirk Barton.
Barton (6'5", 310 lbs.) was a seventh-round pick of the Bears this past April. He was a three-year starter at Ohio State. Here is an excerpt from his NFL Draft Prospect page:
Compares To: MIKE GANDY-Arizona...Barton is a lunch pail type who quietly goes about his job. He is effective at sustaining and widening the rush lanes and works well on combo blocks with his guards. He is more of a waist bender, which makes him look sluggish on pulls and traps, but he shows better quickness in his pass set to neutralize edge rushers. He needs to develop a stronger hand punch and has some slight durability concerns.-----
In other news, the Thursday practice report was issued and there were no changes made to it from Wednesday's version. Miami again had no players listed as injured.
