The status of fullback Rob Konrad for the Tennessee game is in question because of what an NFL source said was a staph infection. Konrad, who suffered a bruised knee earlier in the preseason, didn't travel to Friday's exhibition game at New Orleans because of what coach Dave Wannstedt described as an injury-related absence.
In light of the offseason retirement of tailback Ricky Williams, Konrad is expected to play an expanded role in the offense this season.
The Dolphins appeared to brace for Konrad's potential absence by keeping rookie Doug Easlick on their 53-man roster and claiming fullback Jamar Martin off waivers from Dallas. Easlick is a college free agent from Virginia Tech.
Martin is a 2002 fourth-round draft pick who played in 14 games for Dallas last season.
Also claimed was cornerback/kickoff returner Lamont Brightful from Baltimore. Brightful's 24.7-yard kickoff return average was third-best in the AFC last season, but struggled this preseason with the Ravens.
To make room for Martin and Brightful, defensive tackle Tony Brown and released cornerback Jimmy Wyrick were waived.
