Pittsburgh Steelers wide receiver Antonio Brown was ruled out of Monday night's game against the Kansas City Chiefs, NBC Sports' Pro Football Talk reported Saturday. Brown sustained a high ankle injury during last Sunday's win against the New York Giants. A source told Pro Football Talk that Brown could miss a few games because of the injury. The injury was reported by the team as not serious, but the sources said it is worse than believed. Emmanuel Sanders, who was fined $15,000 this week for faking an injury, will start in place of Brown. Sanders appealed the fine. The Steelers were also fined $35,000.
