First, LB Justin Rogers was back out on the practice field. The Chiefs signed him twice in October. The first time he was on the team for a few days and the next time he was signed and then released again within 24 hours.
G Mike Goff was not at practice and, as Looney points out, connecting the dots would suggest Goff has landed on IR (but still no confirmation from the team). It's unlikely he was released while he was injured (which would entail an injury settlement). He was battling a shoulder problem the last couple weeks which eventually helped Andy Alleman land the starting job at right guard last Sunday.
McGraw returns but Morgan stays on the first team
Now this is interesting. FS Jon McGraw has returned to the practice field after missing the last two-and-a-half weeks with a leg strain. SS DaJuan Morgan was taking his place at FS while he was injured but - surprise, surprise - Morgan continued with the first team today.
Linebackers banged up
Vrabel's the only one of those players on the first team, which was filled by Andy Studebaker today.
