Help! Forgot to save starter

I had three loaves of sourdough in the oven and was upstairs, about to step into the shower, when it suddenly hit me that last night, when I mixed the dough, I forgot to hold back any of my starter - all of it went into the bread.

So I raced downstairs, yanked a loaf out of the oven, broke through the crust that had started to form, and scooped out some of the inside, which was very warm but not hot.  All things being equal, I think it would be no problem to feed this dough and turn it back into starter.  However, it's a pretty salty loaf, 1 T in a kilo of dough, so I'm thinking that may make it more difficult. 

I've been baking sourdough on a regular basis for well over a year, and this is the first time I've failed to reserve some starter.  I really liked that starter, so am hoping for some input/advice on how to coax it back to life.  Thanks in advance!
