When asked about Aiyuk, Shanahan said the following, per Matt Barrows of The Athletic:

“We haven’t seen him in forever. I haven’t seen him in a month, and the same with our team. So (putting him on the reserve/left team list) hasn’t been an issue with our team at all. We’ve kind of been plugging away, and it’s no big deal. It’s just something we’ve been used to for a while.”

Shanahan then said, “I literally haven’t had to think about B.A. or had a reason to think about him in a long time.”

Yeah Shanny Jr is fed up.
