Fantasy Football: Concussed Athletes Have Double the Risk of Leg Injury


Concussions Injure More than the Brain

It’s been a busy year for sports medicine journals when it comes to covering concussion research. Two studies that have some important fantasy football implications are linked below:

Acute Lower Extremity Rates Increase Following Concussion in College Athletes Concussion Frequency Associates with Musculoskeletal Injury in Retired NFL Athletes

If you’re new to the blog because you’re a Fantasy Football Fan, this is all you need to know from those studies:

College athletes who had a concussion have DOUBLE the risk of having a lower extremity injury within a year than non-concussed counterpartsThese numbers increase exponentially with every successive head injury. i.e.- a player with 3+ concussions can have a 75-165% increased odds of a serious musculoskeletal injury.

Why Does this Happen? (Fantasy Football Fans Can Skip to the bottom for my predictions)

Just to keep things simple, I’ll say it like this. Whenever you injure your brain, your body loses a small part of it’s ability to control movement.

Athletes rely on precision timing for movements of their musculoskeletal system. Just the act of jumping requires your brain to send information to your foot, ankle, hip, and knee muscles to prepare to land. The timing of how all of these muscles fire is important because it:

  1. Protects the ligaments and cartilage from unnecessary sheering
  2. Allows the lower extremity to prepare for the next movement

If you suffer a brain injury and you lose some of this motor control, your joints can have moments where a weakness can be exposed. This loss of motor control is likely what leads these athletes to have more sprained ankles, torn ACL’s, and pulled hamstrings. Football is a brutal enough sport as it is. Even ball players with a clean history of injury will get hurt simply becaues of the violent and rapid pace of the game. If you combine that with a brain that is responding just a split second slower, you have a recipe for greater injury, even without contact.

Fantasy Football Injury Tips

Fantasy football injuries have cost me dearly the past 2 years. Because of that, I decided to do some homework on what things tend to make a player a bigger risk.

I was looking at some of the data that was putting out, and it doesn’t appear that they account for this increased risk quite yet. That being said, the numbers they crunch and predictions trends that they notice are phenomenal. So here is your factors to look out for when screening players for injury:

  1. More years in the league = more durable. It’s counter intuitive, but think of it like natural selection. If a player is still in the league, they are likely the ones tough enough to handle it. Rookies and 2nd year players have a much higher injury risk than tested veterans. Just ask Frank Gore and Marshawn Lynch.
  2. Injury Rap Sheet – If you see players that are constantly on the “Questionable” status before a game, they are more likely to get hurt at some point in the season. While coaches play games with a player’s status, the Sports Injury Predictors noticed that the more times a player’s status is in doubt, the more likely they will fall during the season. Look at a player’s status history to make a judgement call on similar players. has a great list here.
  3. Size – Pretty straight forward. Guys with less mass are generally more prone to injury in contact sports.

Dr. Chung’s Concussion Risk List

I took a look at the concussion history of key players in fantasy football. I focused my list on wide receivers, running backs, and tight ends because these are the guys where their history of concussion might make a difference on who you select. With quarterbacks…you’re probably going to pick who you want to pick regardless of what their injury history looks like.

However, choosing between Le’Veon Bell, LeSean McCoy, or Adrian Peterson, their concussion history and liklihood of lower extremity injury may become the thing that makes or breaks your draft pick.

I can’t say enough how much my life has changed under Dr. Chung’s care. After 10 years of chronic pain and being dismissed by my neurologist, I came to Dr. C. He was caring, and really listened. After only 2 visits, I have already had a tremendous reduction in my pain! I feel like a new person.

I can't say how much Dr Jonathan Chung has given me back a full quality of life. Migraines was my daily focus, brought my on by a minor car accident few years before. I thought I was going to live with pain medications for the rest of my life. After seeing 2 neurologist prior I was convinced that was my life. But I never stop searching for holistic approaches which led me to Keystone Chiropractic. Thank you.
