Detroit signed Ihedigbo to a $3.1 million, two-year deal before last season, and the veteran safety started 13 games and intercepted a career-high four passes. Agent Marc Lillibridge says Ihedigbo's potential absence wouldn't really be a holdout, since he'd be skipping voluntary activities.
Ihedigbo is due a base salary of $1.1 million on his current deal.
The Lions announced the signing of linebacker Brandon Copeland on Tuesday.
