Grant left Monday night's game against Minnesota after suffering a concussion.
Grant took a shot in the first half and was knocked out of the game after being diagnosed with a concussion. Prior to his departure, he returned two punts for a total of five yards while turning a pair of rushing attempts into another 17 yards. Grant's absence came back to bite the Bears later in the game, as Damiere Byrd muffed a punt at the start of the fourth quarter. Grant will have a short week to recover and will need to pass through the league's concussion protocol to play Sunday at Seattle.
