The Lions put fullback Jon Bradley on the injured reserve today. Bradley missed the last preseason game due to a shoulder injury, but it was never thought to be anything serious. Obviously that's not the case as Bradley is now out for the season.
In another move made today, wide receiver Taye Biddle was released by the Lions, opening up a second spot on the roster. The first open spot went to free agent tight end Clark Harris. The second went to wide receiver Eric Fowler, who was on the Lions for a few days back in July.
With Bradley out for the season, Jerome Felton will make the 53-man roster for sure. I would imagine Sean McHugh makes the roster as well. Back when Teddy Lehman got shelved for the year I said that injuries would make decisions for me on my roster predictions, and that is exactly what has happened at the fullback position.
