On Tuesday, the Cardinals signed LB Vic So'oto to the 53-man and added LB Bruce Taylor to the practice squad.
Then came Wednesday, when the Cardinals relegated LB Alex Okafor (biceps) to injured reserve and promoted LB Kenny Demens from the practice squad.
The flurry of signings came to a close Thursday morning, when Nash was re-signed to the Cardinals' practice squad. That gave Arizona eight practice squad players and 53 active-roster men.
Chances are the Cardinals aren't done wheeling and dealing just yet. This was all mostly a stopgap until Daryl Washington returns Monday, and Arizona's braintrust will determine what spots need to be filled and by whom. If Moch can hold his own against the Bucs, he could stay up. But don't expect this bunch to be the linebackers for the next 13 games.
