Chiefs announce a flurry of roster moves including waiving a player who they just claimed days ago

In addition to the moves on the 53-man roster, the Chiefs also made a trio of moves on the practice squad. They signed former seventh-round pick CB Nic Jones and  former Patriots QB Bailey Zappe to the practice squad. In a corresponding move, the team released RB Emani Bailey from the practice squad. That leaves RB Keaontay Ingram as the only running back on the practice squad for Kansas City. 

Why did the Chiefs waive CB Eric Scott Jr. days after claiming him?

This feels like a bit of a strategic move from Chiefs GM Brett Veach as opposed to something like a failed physical or a change of heart. Should CB Eric Scott Jr. clear waivers, which is highly likely seeing as the Chiefs were the only team to submit a waiver claim, it's reasonable to expect that he'd join the practice squad as well. There he'll have an opportunity to learn the playbook and get up to speed without taking up a 53-man roster spot. He could potentially be elevated to the 53-man roster down the line and become a key contributor on both special teams and the defense. It does leave the Chiefs a little short on CB numbers for Week 1 if Nazeeh Johnson and Josh Williams continue to deal with minor hamstring flare-ups.
