This comes mere days after the Lions hosted him for a workout last week. Detroit was trying to figure out how to replace Ameer Abdullah, whom the club reportedly fears could be lost for the season with a torn ligament in his foot, and kicked the tires on Bell with a workout. Now Bell will help replace Jeremy Langford who is expected to miss 4-6 week with a bad ankle. The Bears aren't sure of KaDeem Carey's status heading into this week and perhaps didn't want Jordan Howard to carry a large workload. Raheem Mostert was Chicago's only other back.
