Several bout changes announced by the UFC

The UFC on Fox 3 card has been forced into a late change after Thiago Tavares suffered an injury ahead of his bout with Tony Ferguson.
The opponent swap marks the second change of opponent for Ferguson, who had originally been slated to square off with veteran Dennis Hallman. Instead, Ferguson will now face Michael Johnson, on a card headlined by Nate Diaz v Jim Miller.
At UFC on FX 3 Leonard Garcia has been slated to fight Matt Grice in a featherweight matchup. UFC on FX 3 takes place on June 8 and features Ian McCall's rematch with Demetrious Johnson.
Brazilian sensation Erick Silva also expects to be on that card after tweeting that he will not get his wish to fight in Brazil at UFC 147. An opponent is yet to be named for Silva.
Elsewhere, at UFC 148 which features Tito Ortiz v Forrest Griffin and Michael Bisping v Tim Boetsch, a lightweight battle between Gleison Tibau and Khabib Nurmagomedov has been announced.
Two lightweights riding hot streaks, Tibau won all three of his bouts in 2011, while Nurmagomedov has never tasted defeat as a professional and owns all but four of his career victories by either knockout or submission.
And at UFC 147, headlined by Anderson Silva v Chael Sonnen, the man widely credited for inventing the anaconda choke will have his first UFC fight. Milton Vieira is set to meet Felipe Arantes, according to the UFC's Brazilian Twitter account.
