Jack was involved with England after the sad demise of his beloved Wasps.
Eddie Jones has a 36-man squad for the autumn internationals, but the flanker is without a club after the administrators took over.
He was one of 167 people made redundant by the club.
It's difficult to think that all has been taken away.
The emotions felt by the Wasps squad when they realised the gravity of the situation were outlined in an interview with the radio station.
He said it was hard to describe how it felt.
Everyone was completely stunned when the administrators talked about how to claim redundant pay.
Everyone in that room, as of that minute, no longer had a job at the club, and who knows what the future holds for everyone individually and also the club, you think in your head, "Have I actually lost my job?"
It was frightening to tell you the truth and upsetting.
Despite the ominous signs over the summer, with Wasps owing tax as well as default on a bond repayment, Willis still hoped a resolution could be found to save the club.
He admitted that on the surface it wasn't looking good, but he always believed someone would solve the problem.
We came in expecting to be told administration was official, not that we were going to be made redundant.
Despite the brutal reality of the situation afflicting his boyhood club, he has tried not to harbor resentment towards those who presided over the slide into oblivion.
He said that he can't change anything.
It's done now and I can't change anything. I just want to remember how grateful I am after this decision has been made.
The club gave me the chance to play with my brother and create lifelong friends.
The main thing for me at the moment is to think about the fond memories.
After the November internationals, he has yet to make a decision on his future, and warned about the difficult landscape facing out-of-work players.
He said that in a perfect world, we would all move somewhere together, stay with my brother and stay with my friends.
Some of the pay cuts are 75%. It would not be considered in any other walk of life. It's our dream to play a sport.
You have to be hopeful that we can all get through this season. It will be very difficult for a lot of people.
He wants to play his way back into the England team and add to his four caps by playing against Argentina, Japan, New Zealand and South Africa at the end of the year.
He said he has five weeks to focus on something that is the culmination of his career and something he has always wanted to be a part of.
You have an agent to look out for you because you don't have a club. My agent tells me to focus on the field and train well.
I have a chance now. I only have one thing on my mind, and that's England. My family haven't seen me play in an England shirt so that's a motivation for me.
I can promise you that I will be giving everything to get that opportunity.
