The Arizona Cardinals sent Al Johnson to the injured reserve, ending his season and thrusting Lyle Sendlein in the starting center job for good. The Cardinals also moved Pat Ross from the practice squad to the active roster and cut Oliver Celestin. That's some what of a surprising me because it leaves the team with only 52 players on the roster. They also cut Anthony Oakley from the practice squad meaning that there are two spots avaliabe there. Next week should be a busy week as they scramble to fill both units. Veterans, like Celestin, can be signed next week with little risk because they're contracts aren't guaranteed after week one.
