“We carefully monitor player injuries,” Signora said. “There is no evidence that the new work rules have had an adverse effect on the injury rate or that injuries have in fact increased.”
And with the ACL injuries, the research by Quintiles/Outcome shows the opposite.
This season through 13 weeks, about 68 percent of ACL injuries involved contact with another player. The percentage in the four previous seasons ranged from 67 percent in 2009 to 55 percent in 2012.
A breakdown by positions showed one tight end, one wide receiver and one quarterback had contact-related ACL injuries through 13 weeks this season. That compares to five such injuries combined at those positions in 2012 and four in 2011.
For offensive players in general, there have been six such injuries in 2013 through 13 weeks, compared to 10 in 2012, eight in 2011, nine in 2010 and six in 2009.
On defense, there were six ACL injuries involving contact with another player. This compares to nine such injuries in 2012, 10 in 2011, nine in 2010, and seven in 2009.
For special teams, there were four ACL injuries involving contact with another player as compared to two last season and four in 2011.
