Many more concussions are being reported in the NFL this season, which the league considers evidence that players and teams are taking head injuries more seriously. According to NFL data obtained by The Associated Press, 154 concussions that happened in practices or games were reported from the start of the preseason through the eighth week of the 2010 regular season. That is an increase of 21 percent over the 127 concussions through the eighth week of the 2009 season, and a 34 percent jump from the 115 reported over the same span in 2008.
