Cardinals awarded LB Keiser off waivers; add six to practice squad

A day after getting down to their initial 53-man roster, the Arizona Cardinals made more moves. On Sunday, the team was awarded linebacker Thomas Keiser - formerly of the San Diego Chargers – in its waiver claim. To make room for Keiser, wide receiver Walt Powell was released. Keiser set career-highs with the Chargers last season in sacks (4.5) and tackles (20). Keiser set those marks in 12 games (three starts). Keiser signed with the Chargers last season and spent the first four weeks of the regular season on the practice squad before being signed to the active roster on Oct. 2. Keiser first entered the league with the Carolina Panthers as an undrafted free agent from Stanford University in 2011. Keiser played 12 games in his first two seasons with the Panthers. As a rookie, Keiser had four sacks in eight games. The team also announced six players who were added to their practice squad: linebacker Jonathan Brown, wide receiver Brittan Golden, tight end Andre Hardy, cornerback Jimmy Legree, tackle Kelvin Palmer and guard/center Anthony Steen. All six players were part of Saturday’s 53-man cutdown.
