It all depends on your REALISTICAL goals and the ability to recover. If you are going to make additional STRENGHT training i dont see the problem to make it in the morning and than to hit the gym at afternoon. Youll have enough time to recover.But of cource you must make clear for your self what your goal is and keep in mind that you have limited recovery abilities! You must make the technique after the warm up(if you make it after the sparing/bag work you wont be able to concentrate and you will learn bad form too). And as Scrap says you must train with your head. If you dont feel it right back off.
