Heisman Trophy winning quarterback Johnny Manziel has left his role as college coach/counselor at the 2013 Manning Passing Academy due to illness, according to camp officials.
Reports initially surfaced suggesting the Texas A&M passer had been chucked out by legendary NFL quarterback Archie Manning due to "partying", but that story has since been denied.
The official line is that Manziel left the camp after missing several meeting and practice sessions due to illness.
And on Sunday Paul Manziel, the player's father, told the Dallas Morning News that his son was recovering from dehydration.
A camp spokesman from the Manning Passing Academy released this statement, as reported by ESPN: "Johnny Manziel did participate in some activities in the 2013 Manning Passing Academy as a college coach/counselor.
"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 from him to go home a day early."
The camp, run by the Manning family including Denver Broncos star Peyton Manning and brother Eli Manning, took place at Nicholls State University in Louisiana.
It has been running for 18 years, and this year took place from Thursday evening to Sunday - Manziel left on Saturday afternoon after he was absent from the morning practice.
But NFL superstar Peyton Manning still had good words for the 20-year-old Aggies star - nicknamed "Johnny Football".
"I enjoyed meeting Johnny," said Peyton Manning. I can remember a 20-year-old Eli [Manning] missing a meeting [at camp] 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."
