It was an obvious penalty, so why would Brown needlessly get himself pulled for the rest of the game to undergo concussion protocol? The Steelers had no timeouts and a FG from that spot would have been 1 yard away from Boswell's career long. The best out route runner in the league was certainly an expendable part of the offense in that situation.
