After going 1–1–1 in her first three bouts, Toughill won five straight fights before losing due to illegal hits to the spine in the finals of the 2004
Smackgirl World ReMix Tournament to
Megumi Yabushita. She competed once more and scored a technical knockout victory over Jen Case in 2006. In 2007, Toughill retired from both boxing and MMA. Toughill came out of retirement from MMA and fought
Jan Finney on November 20, 2008, at Palace Fighting Championships 11. Despite cutting over to make the contracted weight limit, Toughill was victorious and later went on to defeat Karen Williams and Emily Thompson in subsequent events for PFC after a fight with Adrienna Jenkins was cancelled due to injury.
Strikeforce Toughill was set to make her
Strikeforce debut on November 7, 2009, at
Strikeforce: Fedor vs. Rogers in a rematch with
Marloes Coenen, whom Toughill defeated in 2004. However, she later withdrew from the fight due to an undisclosed medical condition. On March 18, 2010, Toughill announced that she was planning to leave
Strikeforce. She had been scheduled to compete on the undercard of
Strikeforce: Nashville on April 17. However, in a second posting on April 9, 2010, Toughill attributed the disagreements with Strikeforce to misunderstandings and stated that she would be staying with the promotion. Toughill was scheduled to face Shana Olsen at
Strikeforce: Houston on August 21, 2010, but the fight was cancelled due to concerns over Toughill's ability to make weight. According to Strikeforce CEO Scott Coker, Toughill's next fight will not take place in Strikeforce, but she remains a part of the promotion's roster. Toughill was offered to face
Cristiane Santos for a bout in 2010, but the fight never came into fruition.
Post-Strikeforce Toughill was scheduled to compete outside of Strikeforce against China's Bao Yu Dan at Martial Combat 9 on September 15, 2010, in
Singapore. However, on September 13, Toughill withdrew from the fight after citing a broken
clavicle. Toughill returned to active competition after nearly two years at Freestyle Cage Fighting 46 on April 9, 2011. The fight was against Ashley Sanchez at a catchweight (per Toughill's request). Toughill lost the fight via unanimous decision. Toughill agreed to face Anna Barone at BlackEye Promotions 5 on October 1, 2011, in
