Bowens is expected to miss most of the 2003 season, although it's believed he could be back by November.
The injury was another setback for Bowens, who battled injuries throughout the 2002 season.
In other, more positive, news:
-- The Dolphins re-signed wide receiver Oronde Gadsden, who agreed to a one-year deal for the veteran minimum of $530,000. Gadsden had been hoping to land a more lucrative deal as an unrestricted free agent, but struck out despite drawing some interest from teams such as Jacksonville, Minnesota and New England.
-- The Dolphins announced that the Marks Brothers, Mark Clayton and Mark Duper, will be inducted into the Dolphin Honor Roll at the halftime of the Monday night game against the Philadelphia Eagles Dec. 15.
Duper and Clayton will be the first Honor Roll inductees since Dan Marino in 2000.
