Stout out, Cerrone in versus Dennis Siver at UFC 137

Donald Cerrone has decided to “cowboy up” for the third time in six months after yesterday’s announcement that Sam Stout had backed out of a scheduled scrap with Dennis Siver in October due to undisclosed reasons. Cerrone is coming off back-to-back wins over Vagner Rocha in June and Charles Oliveira in August, the latter of which he earned “Knockout of the Night” honors in.

Cerrone’s addition to the October 29 event was announced through the UFC’s website.

The 16-3 lightweight has looked sharp since joining the UFC’s ranks after a successful run in WEC with five straight wins including a trio in the Octagon. Cerrone should provide an interesting stylistic match-up for Siver when the two meet in Las Vegas, as he not only possesses multi-level striking but has won the bulk of his fights as the result of his impressive ground skills.

Siver is also in the midst of a streak going four-for-four since losing via decision to Ross Pearson in March 2010 including wins over Matt Wiman, Spencer Fisher, and Georges Sotiropoulos.

UFC 137 is headlined by Georges St. Pierre defending his welterweight championship against former Strikeforce title-holder Nick Diaz.
