It is my impression that you will be able to increase the weight akin to a linear progression, especially if the bruise does not swell any further. Your own experience ought to dictate how quickly you increase the weight; if you have a 455 pound deadlift, I assume that you know quite a bit about what you are doing. Hematomas are simply subcutaneous bleeding, and you made it bleed more. However, in an area with adequate blood supply and lots of muscle such as the upper quad, I bet that it heals rather quickly and do not anticipate that you will have any major stalls in your training.
