CHICAGO — The latest round of class-action concussion lawsuits against the NCAA and major college football conferences were filed by former college football players from Florida State, Miami, Florida, Mississippi State, Kentucky, Louisville and Murray State.

The lawsuits were filed in federal courts Wednesday by Chicago-based attorney Jay Edelson. The seven lawsuits increase the total number to 22 filed since May.

The players are seeking damages for injuries they claim are the result of mishandled concussions they suffered while playing college football.

In most cases the lawsuits name the NCAA and the conferences in which the schools competed. State laws protect most schools from being sued. The University of Miami, a private school, is named in the lawsuit filed by former defensive back Ryan Hill, who played for the Hurricanes from 2006-2010.
