...before the first rep!

What!?
I was setting up the weights I needed for my first workout of NROL4W. Somehow I managed to pull my quad, vastus lateralis?, before I even started the workout. My kids have had the flu and I'm under the weather myself. So, I must be out of my mind as well as off my game.
I thought about posting this in the injury area, but I'm pretty sure it's just a tear and should be fine in a week. I'm posting here because I'm curious to see if there's something I can do while I wait until next week to start the program. I do not want to lose my conditioning.
Right after the tear I did the parts of the workout I could do: pushups, rows and prone jack-knives. I felt like I didn't do enough (and was SO bummed out about my tear) so I did overhead presses and calf raises.

Then I worried that maybe I shouldn't do the exercises in the first week before I officially start the program. That's what made me post here.
What kind of workout would you do if you were me? Should I just do the upperbody portion of NROL4W week 1, then repeat the week when my leg is better? Or should I skip weights (noooo) this week? Make up my own upperbody and core program?
Any help is greatly appreciated.
Thanks!!
