QB Depth Concern After Mertz Injury

Third-string QB Graham Mertz left the preseason opener with a knee injury (likely ACL). Davis Mills had to return and played most of the game. No fourth QB on roster; team recently worked out Henigan and Haener. A new article proposes trading for Mason Rudolph as a potential solution. This is a significant blow to QB depth; the team will need to sign another QB for preseason reps.
