Rumors continue to fly around that former UFC heavyweight champion Brock Lesnar will return to the UFC for one more match – and if true, Shane Carwin wants to face him.

Carwin, who lost to Lesnar back in 2010 in a bout for the UFC heavyweight title, made it known on Twitter that he desires to be at UFC 168 Saturday night.

The UFC has a special announcement planned for Saturday, which we will carry live coverage of.
