"Tight end Jeremy Shockey did not participate in the New Orleans Saints' minicamp practice Friday because of back problems, according to the New Orleans Times-Picayune.

Saints Coach Sean Payton said Shockey was withheld from practice as a precaution and his absence was not related to a weight-room episode last week, according to the newspaper.

Payton said Shockey did not suffer a seizure last week, as had been reported. According to the Times-Picayune, Payton said Shockey had low blood sugar, was dehydrated and fainted."
