Chael Sonnen let it be known that Wanderlei Silva is on the clock, sending him a simple message via Twitter Thursday afternoon.
“Tick…Tick…Tick,” Sonnen posted.
On Wednesday evening, the former UFC No. 1 contender informed Silva that he had 24 hours to accept his challenge for a fight. He even offered to put up a portion of his purse towards Silva’s hometown.
Silva, coming off a win over Brian Stann, has yet to respond. The former PRIDE champion has been fairly inactive on Twitter in the recent days.
