Las Vegas Raiders linebacker Luke Masterson (concussion) was forced to exit Monday night's game against the Detroit Lions due to a concussion. He left in the second quarter and was taken into the tent to go through some concussion protocols and he didn't make it through them to get back on the field. For the most part, the Lions were able to keep getting down the field into scoring range in the first half. The banged-up defense will be one to monitor as the game goes on.
