Ambrose made his televised debut on the July 3 episode of FCW where he challenged Seth Rollins, another prominent independent wrestler. Ambrose and Rollins had their first match for the FCW 15 Championship in a 15-minute Iron Man match on the August 14 episode of FCW which ended in a draw with neither man scoring a fall, so Rollins retained the title. A subsequent 20 minute rematch for the title two weeks later resulted in a similar 0–0 draw. A second 30-minute rematch for the title on the September 18 episode of FCW went to a time limit 2–2 draw and the match was sent into sudden death rules, where Rollins scored a pinfall to win the match 3–2. Of note, an entire episode of FCW was dedicated to hyping and showing the third match in the series. Ambrose finally beat Rollins in a non-title match in the first round of the Super Eight tournament to crown the new FCW Florida Heavyweight Champion. However, Ambrose was unsuccessful in the tournament final as Leo Kruger won the fatal four-way match. Ambrose also cost Rollins his FCW 15 title by attacking Damien Sandow during his title match with Rollins, causing a disqualification in the deciding fall. Ambrose then unsuccessfully challenged Sandow for the FCW 15 title, before Leakee defeated both Ambrose and Rollins during a triple threat match to determine the number one contender to the FCW Florida Heavyweight Championship.
