Alexander Volkanovski is coming off a fight in which he lost — and was congratulated for it. Now he's back in his more familiar featherweight division, where he won five title fights, to take on interim champion Yair Rodriguez (16-3) on Saturday for the belt in UFC 290. Having gone up in weight and come back down, Volkanovski (25-2) said the experience of trying to add more bulk should serve him well.
