William Kershaw, a 6-3, 250-pound product of the University of Maryland, is back as insurance in the event that the health problems of starters Channing Crowder and Akin Ayodele become more significant.
Ayodele has battled a back problem for a few weeks now, and Crowder has had issues with a knee. In fact, a published report indicated Crowder underwent an MRI after Sunday's game against New Orleans.
Kershaw's addition gives the Dolphins 10 linebackers, which is an abnormally large number, even for a team that runs a 3-4 defense.
And that's not even counting Matt Roth, who began practicing last week after six weeks on the Non-Football Injury list and could wind up being activated if the Dolphins decide he can help this season.
It will be interesting to see whether Crowder and/or Ayodele are at practice on Wednesday when the Dolphins begin their full-blast preparations for Sunday's game against the New York Jets.
Kershaw appeared in one game with the Dolphins last season after being promoted from the practice squad in December. Against Kansas City, he forced a fumble on a kickoff return and it was recovered by the Dolphins.
Kershaw also played one game in 2006 with Kansas City and one game with Houston in 2007.
