Heisman Trophy winner Texas A&M quarterback Johnny Manziel left the 2013 Manning Passing Academy early due to an unspecified illness, according to a statement, reported ESPN.com's Chris Mortensen.
Manziel recently missed assigned meetings and practice sessions during the annual camp hosted by Eli and Peyton Manning.
"Johnny Manziel did participate in some activities in the 2013 Manning Passing Academy as a college counselor/coach," the statement read. "After missing and being late for practice assignments, Johnny explained that he had been feeling ill. Consequently, we agreed that it was in everyone's best interest for him to go home a day early."
Apparently that cause of the illness was dehydration, according to Manziel's father, Paul, via the Dallas Morning News. he's "resting and recuperating from dehydration," the father said.
Peyton downplayed the early exit, saying "I enjoyed meeting Johnny," Manning said. "I can remember a 20-year-old Eli missing a meeting and catching some flak. We always have counselors who leave early. Johnny was great with the campers for the time he was here. He had to leave early. I wish him the best and I want him to come back as a counselor next year."
