Damar Hamlin is continuing to make steps in his road to returning to NFL action -- on Tuesday, the defensive back got in some work at Bills practice ... and he looked GOOD!!!
Just over four months after he went into cardiac arrest on the field during a "Monday Night Football" game ... Hamlin was out at Buffalo's organized team activities -- and while he didn't fully participate in the practice, he still showed off some athleticism at the workout nonetheless.
According to reporters on the scene, Hamlin did some calisthenics with his teammates, got in some agility work .
