BOSTON – Had things worked out differently, Yuri Alcantara might be feeling a little more awkward about his upcoming fight with Urijah Faber . Alcantara (28-4 MMA, 3-1 UFC) flirted with the idea of training at the Team Alpha Male gym where Faber (28-6 MMA, 4-2 UFC) hangs his hat. The two might have made for some spirited sparring, but the Brazilian Alcantara, who most recently beat Iliarde Santos at UFC on FX 8, didn’t wind up making the trek for Sacramento, Calif., where Faber’s gym resides. Good thing, because not long afterward, they were booked to fight each other at UFC Fight Night 26, which takes place Saturday at TD Garden in Boston.
