The National Football League seems to be having some success in its efforts to curtail concussions.
Largely due to the league’s changes in kickoff rules, last season overall concussions dropped to 266 from 270 the prior season, according to Edgeworth Economics, a consulting firm. Concussions at kickoff plummeted by 43 percent from 2010 to 2011.
Edgeworth, which studied injury data provided by the players’ union, said that the decline in concussions in 2011 reversed a multi-year trend.
However, recorded injuries increased substantially in 2011, “driven by a large increase in the number of ‘minor’ injuries as classified by the NFL Injury Surveillance System,” according to Edgeworth. There were 1,302 more total injuries.
So-called moderate injuries, in which a player is on the bench for the one to three weeks, increased by 17 percent.
