Jones, one of Carolina's early free-agent additions, was signed to a two-year, $15 million pact in March. He's coming off a career campaign—where he notched bests in combined tackles (39) and sacks (7.0) for the Minnesota Vikings.

Clowney could provide valuable depth for Seattle's offensive line, and he is familiar with Mike Macdonald's system.

The Carolina Panthers have released one of their starting pass rushers from last season, the team announced Thursday, parting ways with Jadeveon Clowney. Clowney was due around $8.53 million in salary this upcoming season, and $2 million of that is reportedly guaranteed. This move frees up $7.78 million in cap space for Carolina.
