Big news day in NFC South

TAMPA, Fla. -- We’ve got news breaking all around the NFC South on Tuesday morning.

I’m out at One Buccaneer Place, where Tampa Bay general manager Mark Domink just said the team is releasing safety Tanard Jackson. Dominik said Jackson, who was recovering from a shoulder injury, failed a physical. Jackson previously served a one-year suspension for violating the league’s substance abuse policy, but Dominik emphasized he wasn’t aware of any new failed drug tests or discipline coming from the league office.

Elsewhere, Chris Mortensen reports that Bill Parcells is unlikely to step in as the coach of the New Orleans Saints. Adam Schefter reports Carolina’s Steve Smith has agreed to a three-year contract extension.

I’ll be back shortly with analysis of all three news developments.
