MONTREAL - Quarterback Johnny Manziel wasn't at the Montreal Alouettes' practice Monday.
A team official said the former Heisman Trophy winner was suffering from the flu.
Manziel practised Sunday, taking reps with the second-team offence.
Antonio Pipkin remains Montreal's starter, having posted a 2-1 record under centre.
Manziel started two games for Montreal, both losses.
He went through concussion protocol following Montreal's 24-14 loss to Ottawa on Aug. 24. But he backed up Pipkin in the Alouettes' 21-11 victory over the Redblacks on Aug. 31.
