The NFL has added eight regional combines to the main combine it stages each year in Indianapolis. The regional combines will begin Jan. 28 in Los Angeles and also will be held in Houston, Baltimore, Tampa, the New York area, Chicago, Atlanta and Cleveland through March 17. The Indianapolis event is at the end of February. Players who attend a regional combine could be invited to a super-regional at Ford Field in Detroit on March 30-31. That event will be attended by NFL team scouts and player personnel directors.
