Shaun Rogers has not participated in the Browns' off-season workout program this week, which likely indicates the Pro Bowl nose tackle has not patched up his differences with new coach Eric Mangini, ESPN.com reported.
The workouts are considered voluntary, but Mangini planned to use Monday's start of the sessions to address the team for the first time.
A rift between the two started when Rogers felt he was ignored by Mangini, first in the Berea weight room and later at a charity event. According to a report, Rogers also took exception to a weight mandate he was given for the off-season program.
Acquired last March in trade from Detroit, the Browns signed Rogers to a six-year, $42 million contract that reportedly carried a $6 million roster bonus due this month.
