Thanks to a tip from LTownChiefsFan, we've learned that the Kansas City Chiefs have scheduled a 4:30 CST teleconference to announce the signing of a free agent.
Of course, continuing with the theme of mystery, we don't know who that player is.
There is some speculation going on in this FanPost. With a teleconference scheduled, it's unlikely that this is a no-name signing.
Kent Babb over at the Red Zone is in on the speculation game and even placed his odds on who the signing might be:
1. Pace, 4-1
2. Holt, 5-1
3. Engram, 6-1
The guys at 810 are thinking it might be a wide receiver. Bobby Engram visited the Chiefs at the beginning of the month.
Continue the speculation in this thread and we'll have some more information on the mystery signing shortly after the announcement.
