Foster Moreau is back doing what he loves ... the Saints tight end took the field for New Orleans offseason workouts on Tuesday -- the first time he's been able to practice since his March cancer diagnosis.
The 26-year-old participated in Day 1 of the Saints' organized team activities ... and he looked like he hasn't lost a step whatsoever.
The former Raider caught balls, ran crisp routes ... and got in some blocking work too.
Of course, he spent a lot of the afternoon snagging passes from new Saints quarterback Derek Carr .
