The best of Friday’s update includes two in-depth stories about how concussions have affected two high school football players:

* In a good human interest article, the San Jose Mercury News wrote about the football-playing son of San Jose State’s coach. His dad was coaching against Stanford while he was competing in a high school game and suffered a serious head injury. It’s a story that is unique because of its plot twists and one to which parent/coaches can relate.

* According to KXAN-TV, a former high school player in Marble Falls, Texas, has sued his coach after he claims that multiple concussions have left him disabled. The player’s suit alleges he suffered as many as 30 concussions under the coach’s watch. He said those concussions also caused multiple Division I colleges to pull scholarship offers.

* Staten Island Live wrote about how one group has begun free concussion testing in that New York borough.

* The Naperville Sun reported on a Chicago-area hospital that is working on programs to limit concussions for young athletes before they happen.

* In the courts, ESPN.com reported the NFL is at odds with its insurers over the league’s defense strategy in the concussion case brought on by more than 2,500 players combined.

* In NFL injury on-field news, Miami Dolphins running back Daniel Thomas still is not cleared to play after a concussion, and New York Jets cornerback Darrelle Revis has come out of his “fog” but has been ruled out for Sunday’s game after suffering a “mild” concussion last week.
