UPDATE: VITOR/ANDERSON OFF – NOW CONFIRMED

Tatame is reporting here that Vitor Belfort has a shoulder injury which may necessitate the postponement of his fight against UFC middleweight champion, Anderson Silva.

The report appears to be based on statements attributed to Belfort’s karate instructor, Jayme Sandall. When Tatame contacted Anderson Silva for comment, neither he nor his camp confirmed knowledge of any injury. If the reports prove true, it will mark the second time this bout has been delayed.

Look for more details to surface from Brazil in the coming days.

Updated, 6:33pm EST: Dana White indeed confirmed that Vitor is out and the fight is off via a message on his twitter on Thursday afternoon.
