Safety Chuck Clark has been a team leader and integral part of the Ravens' defense over the past three seasons.

However, the Ravens selecting Kyle Hamilton in the first round, combined with their signing of free agent Marcus Williams earlier in the offseason, has raised questions about Clark's future in Baltimore.

A cryptic tweet by Clark Friday added fuel to speculation that he might be looking for a change of scenery.

There's been no indication that Clark has made a formal trade request, but The Athletic's Jeff Zrebiec said Clark is "apparently unhappy with how a few things have played out this offseason."

When Head Coach John Harbaugh was asked at Saturday's rookie minicamp about Clark's future, he made it clear that he views the veteran as an important member of the team.
