(Berea) - The Browns had to reduce their roster to 53 last Saturday, but the roster continues to evolve as Sunday's season opener against Miami draws near

 Currently the Browns do not have a kicker on their roster, but they are scheduled to give tryouts to kickers Billy Cundiff and Giorgio Tavecchio.

 Cundiff kicked for the Browns briefly in 2009 when Phil Dawson had a strained calf. Cundiff had a Pro Bowl season with Baltimore in 2010. Tavecchio was cut by the Packers last week.

 Some good news at Monday's practice, as top pick LB Barkevious Mingo was able to practice on a limited basis. He continues to recover from a bruised lung.

Trent Richardson is the "main man" when it comes to the Browns running game, but after losing Montario Hardesty and Dion Lewis to injuries and releasing veteran Brandon Jackson, the question is, who will backup Richardson.

The Browns signed two runningbacks over the weekend, Bobby Rainey who was cut by Baltimore and Dennis Johnson who was released by Houston.

 The Browns host the Dolphins Sunday at 1pm.
