Hot weather — even by south Louisiana standards — is causing the New Orleans Saints to change their training camp schedule. The club announced Tuesday evening that it has decided to shorten the time the team is scheduled to practice on outdoor fields during days when training camp is open to fans, “in an effort to protect the health and safety of Saints fans, players, coaches and staff.” Temperatures have reached the mid- to upper-90s in New Orleans the past few days and the National Weather Service has issued excessive heat warnings for the area.
