PHILADELPHIA (KYW Newsradio) -- Concussions and traumatic brain injury in football is widely studied because of knowledge about CTE and long-term effects of damage. 

When we think of concussions, most of us have an image of a dramatic event leading to  a concussion. 

Now, there is a report from the University of Michigan which finds that a single high acceleration head impact that does not lead to obvious concussion may lead to elevations in blood biomarkers associated with traumatic brain injury.  

In addition, the study found that football players who played throughout an entire season without concussion had increases in these biomarkers. 

Scientist are looking at ways to provide regular tests for all players which might serve as warnings, especially if this can regularly occur without concussive symptoms.
