KANSAS CITY, Mo. -- The last time Alex Smith had a concussion, he lost his job as a starting quarterback.
In 2012, when playing for the San Francisco 49ers, Smith was concussed and sat out a game. When he returned the follow week, his starting spot had been given to Colin Kaepernick and Smith never got it back. After that season, he was traded to the Kansas City Chiefs.
So, if anyone has reason to push things, it's Smith, particularly considering that under current circumstances both he and the Chiefs believe he doesn’t have a concussion.
