Once a player on the PUP (physically unable to perform) list begins practicing, the team has a 21-day window to decide whether or not to add him to the 53-man roster.
That means the Chiefs have until November 23, and if this deadline passes, Hali will remain on the PUP list for the remainder of the season.
