NFL concussions rose sharply in 2015

Concussion issues in the NFL continue to be a major problem.

The NFL released data on Friday that displays diagnosed concussions rose by 32 percent this season.

A total of 271 concussions were reported - a figure that includes regular-season games, preseason contests and practices since the beginning of training camp.

That is a sharp rise from the 206 diagnosed in 2014.

The league improved its concussion protocol after there were 261 reported concussions in 2012. The number dropped over the next two seasons - there were 229 in 2013 - before this season's increase.

The NFL didn't immediately comment about the increase.

However, the rise could be tied into increased awareness about the dangers of concussions. Players and coaches have been educated about the seriousness and possible concussions are reported quicker to trainers and medical staff than in previous eras.

Of the 271 concussions this season - 234 occurred in games and 37 in practices.

A total of 92 concussions occurred due to contact with another helmet. There were 29 attributed to contract with the playing surface and 23 due to contact with the shoulder.

Also, knee injuries were up in 2015. There were 56 ACL injuries this season, up from 49 last season, and 170 MCL injuries, a rise from 139.
