Lightheavyweight #1 contender Alexander Gustafsson had some stern words for Jon Jones via Facebook today. Jones apparently has yet to sign the contract to face Gustafsson, and after 4-days of waiting, “The Mauler” has had enough.

Gustafsson vs. Jones II is anticipated to take place at UFC 177 on August 30th, however no official date has been announced yet.
