Defensive tackle Haloti Ngata is expected to be among a handful of Ravens players who will be sidelined for this weekend's minicamp.
He had offseason surgery to repair a minor pectoral tear suffered during the Pro Bowl.
Others not expected to participate in minicamp are: cornerbacks Fabian Washington (knee) and Lardarius Webb (knee) as well as safety Ed Reed (hip).
Cornerbacks Domonique Foxworth and Chris Carr are projected to run with the first-team defense. Tom Zbikowski will likely fill in for Reed.
Backup safety Haruki Nakamura (ankle) likely won't suit up for practices.
It's unknown whether nose tackle Kelly Gregg and linebacker Jarret Johnson will practice. Both had offseason shoulder surgeries.
