NFC West personnel people were busy Monday. Here's what they were up to:
Arizona: The Cardinals released defensive tackle Keilen Dykes. They asked for and received a roster exemption for tight end Ben Patrick. The exemption expires Oct. 19. I would expect the Cardinals to activate Patrick for their Week 6 game at Seattle. They'll want to check out his conditioning level to be sure. NFL rules banned Patrick from team-related activities during his four-game suspension.
San Francisco: The 49ers released return specialist Allen Rossum and submitted a waiver claim for Seahawks defensive tackle Michael Bennett. The NFL awarded Bennett to the Bucs, who had waiver priority based on an inferior record. The 49ers activated receiver Michael Crabtree to make sure the team had 53 players on its roster. Failing to keep 53 players on the roster would have forced the team to release Dominique Zeigler from its practice squad.
St. Louis: The Rams planned to re-sign receiver Tim Carter after placing defensive tackle Gary Gibson on injured reserve. Carter and former Seahawks receiver Jordan Kent had tryouts Monday. The Rams signed linebacker K.C. Asiodu and defensive tackle Chris Bradwell to their practice squad. To make room, they released defensive tackle Adrian Gandy and cornerback Lamar Myles.
Seattle: The Seahawks lost Bennett to the Bucs. The team did not immediately make a roster move.
