The Oakland Raiders held their first practice of training camp on Friday in Napa, Calif., but Trent Richardson didn't participate. Oakland announced the former Alabama All-American had been placed on the non-football injury list.
The non-football injury list is for players who get hurt away from team activities, although the Raiders did not announce an injury for Richardson. His placement on the NFI list also might indicate he did not pass or did not take Thursday's conditioning test.
While on the NFI list, Richardson can't practice with the team. He'll be immediately eligible to practice once the designation is removed.
The NFI designation comes two days after Vic Tafur of the San Francisco Chronicle reported "whispers are that the Trent Richardson reclamation project is not going so well."
