The Chiefs have a couple of safeties on the injured list right now, which may have helped them decide to add some depth at the position.
Gregory was released by the Patriots in February after playing 26 games with the team over the last two seasons. Gregory started 23 of those games, recording 116 tackles, four interceptions and two forced fumbles.
Eric Berry left Chiefs practice early on Thursday with an ankle injury, although coach Andy Reid and others have downplayed the severity of the injury since Berry was removed from the field. Sanders Commings had ankle surgery on Thursday, however, and that absence could stretch a bit longer.
Even with everyone healthy, Gregory would be a viable competitor with Husain Abdullah for the starting spot next to Berry. He’ll get the chance to win that job over the next month or so.
