Detroit Lions practice was delayed this afternoon as teams around the league waited for the official word on the ratification of the new CBA. According to multiple reports, it has in fact been ratified, meaning all players under contract will be able to practice.

Before word came down about the new CBA, the Lions announced four signings and four releases.

Unrestricted free agents Bobby Carpenter and Chris Houston are officially back under contract (Carpenter for one year and Houston for two), as is restricted free agent Cliff Avril. Offensive tackle Isaac Sowells, who worked out for the Lions yesterday, is also now on the team.

To clear room on the roster, the Lions released four players: WR Michael Moore, OG Pat Illig, CB Branden Bufford and CB Brandon Stephens. Moore joined the Lions as an undrafted free agent last year and spent the season on the practice squad. The other three players were signed as UDFAs this year.
