If his TT really is that low, a lot of other endocrine markers should be way off too, in particular, estradiol & DHT should be very low. I think too an LH/FSH scree will be very helpful, as he could have a testicular injury. If that were the case, LH/FSH would be very high and TT would be very low. While it would not rule out a pituitary tumor, it would lessen the urgency of an MRI. Bottom line is that with T levels that far out of range, he needs the consult of a good endocrinologist and not go it alone, as that might just mask a much more serious underlying condition until it's too late.
