Three new names are now official for the "All In" 10,000-seat stadium event in Chicago this September. MJF and Madison Rayne confirmed their spots at a WrestlePro event this past Friday night, teaming up to take on Flip Gordon and Brandi Rhodes. The stipulation of the match called for the winners to advance to the "All In" event, and MJF and Rayne ended up getting their hands raised. Additionally, The Young Bucks officially announced Impact Wrestling Executive Vice President Don Callis will be attending "All In." The decorated veteran tag-team made the announcement after they won the IWGP Tag-Team Championships at the NJPW Dominion event this morning. The two walked over to Callis after their victory and said he was "All In." Callis accepted the invitation. "All In" is scheduled to go down from the Sears Center Arena in Hoffman Estates, Illinois on September 1st.
