It really was something he ate.
But what exactly he consumed that caused Gilles Lezi's kidney ailment remains a mystery.
Although the non-import fullback flunked his Blue Bombers medical due to that lingering kidney ailment, Lezi took part in some drills during the first day of Winnipeg training camp yesterday.
"It's just something that happened last year," said Lezi, who was reluctant to delve into a full explanation. "It wasn't a hit, it was actually something that happened off the field. It happened during the last game of the season when we were playing Winnipeg when I was with Calgary ...
"It was something that I ate and had to go to the hospital. Nothing serious that's going to affect me later on. It doesn't have an effect on me now, they (Bombers) just have to protect themselves. They have to make sure that I'm safe before I get on the field to make sure they're covered."
But the Bombers are trying to determine whether or not the kidney ailment is related to an old football injury.
"It is a weird scenario," said Bombers GM Brendan Taman, who had signed Lezi as a free agent on the eve of training camp. "We want to know what happened and how it happened and how it affected his kidney. With that type of injury, there is no way we can put him on the field until we know more."
Lezi, 27, is still hopeful he will be cleared to practise.
"They asked me to stick around and once they get this stuff straightened out, they'll put me back on the roster," said the 6-foot, 227-pound Kinshasa, Congo native who had joined the Stampeders after failing to make it in Hamilton last year.
"At the beginning, it was (frustrating) and it still is. I'm a competitor, I want to be on the field and show what I have."
