According to the NFLPA, the Bears can get a one-week exemption for FB Obafemi Ayanbadejo, who is eligible to come off the suspended list today.
This would give the organization time to decide what they want to do with Ayanbadejo, and whether or not they will cut a player to make room for him on the 53-man roster.
Ayanbadejo is coming back from a four-game suspension for violation of the league's policy on steroids and related substances. It's not know whether or not the Bears plan on adding him back. They have dressed only one fullback through the first four games, and had two in uniform for only one game last season.
It's doubtful the Bears would bring in Ayanbadejo and not dress him on gamedays. More on this as news comes.
