I'm guessing it's just because they are trying to avoid any double ups on jersey numbers. With the redshirt 4 game rule, dressed redshirts might play in any given game. It didn't used to matter if a redshirt doubled up on a jersey number, now it might. Channelle and Kepouros both are listed as 19 on the roster, so I'm guessing they gave Channelle number 24 for the game, because Purifoy is injured and won't dress.
Purifoy is injured? Where has than been stated?
Yes, I see him on the roster, but haven't heard a peep on gameday.
Purifoy had a carry during mop up time last week.....I think it went for a loss or no gain.
