Previous Pec Injury, Exercise Replacement?

Hey all. So about 1.5 years ago I partially tore my pec throwing a discus, but it wasn’t bad enough to need surgery. Finishing up the 2nd week of the 5/3/1 program and it is getting agitated. Any advice for a replacement exercise going forward?

Whatever exercise you can do - only you can answer that.

I tore my left pec 12 years ago it sucks what exercises agitated it?
