Patrick Mahomes is set to lead his team to a second-straight Super Bowl appearance, as they take on the Buffalo Bills in the AFC Championship Game, on Sunday. After spending much of the week progressing through the league's mandatory concussion protocol, he was cleared to play in Sunday's title game. His availability was certainly up in the air after he was tackled by Cleveland Browns LB Mack Wilson, in last week's divisional playoff game. Mahomes had noticeable trouble staying on his own feet just moments after the play was over.Here’s video of the Patrick Mahomes injury.

It's a multi-step process that starts with the injured player demonstrating success in what's called, "symptom-limited activity", all the way to the final step of "full football activity", resulting in clearance to play in a game.The Divisional Round saw the NFL’s concussion protocol in action.NFL Chief Medical Officer Dr. Allen Sills explains why following the protocol is so important.For more: https://t.co/99q7FWqbAq pic.twitter.com/rrM258lhFN— NFL (@NFL) January 22, 2021The final step is completed after the player has been evaluated by both the team's physician and also an independent neurological specialist, that's been assigned to the team.

Though to add, a player in the protocol can be taken out of the process and cleared to play even as late as gameday.Patrick Mahomes and the Chiefs will face the Buffalo Bills in the AFC Championship Game at 6:40 p.m., Sunday, for a spot in Super Bowl LV, against either the Packers or the Buccaneers.
