Collaros's age and injury expose a fragile QB room with a shaky backup.

Zach Collaros (38) exited late in the 3rd quarter with a suspected upper-body injury after throwing an INT, and backup Dru Brown immediately took a sack, contributing to the 5 total sacks allowed. The Bombers' Grey Cup odds hinge on a 38-year-old QB whose durability is now a critical roster risk, with no proven veteran behind him on the depth chart.
