Haener starts vs Commanders: 1 INT, 5 punts ; Rattler replaced Haener in 2H: led to 19 points

He was the #2 QB earlier in the year when Carr went down and Rattler got the call over him.
Yes, and I remember reports stating that Haener was elevated to the #2 after Carr returned from injury, probably related to Rattlers poor play during those 3 games he started. He played much better yesterday and definitely cemented his place ahead of Haener at this point.
