It's been a mysterious week for the Chicago Bears and Roquan Smith. 

He was listed as an inactive for Week 4 just 20 minutes before the game and had no sign of any injury. 

Head coach Matt Nagy revealed it was for personal reasons and that Smith will be given as much time as he needs. 

Smith was a full participant in Wednesday's practice and confirmed to reporters that he would play in London. The Bears' linebacker like Nagy would only say he was dealing with a personal issue. 

Prince Amukamara made a post on Instargram that has some believing it was influenced by Smith's situation.
