Unified middleweight champion Claressa Shields (10-0, 2 KOs) is reportedly going to debut in mixed martial arts.

According to a report by MMA Junkie, the two-time Olympic gold medal winner has signed an agreement with PFL (Professional Fighters League).

Shields last saw action in the ring back in January, when she dropped down in weight to capture the WBC, WBA junior middleweight titles with a lopsided decision over Ivana Habazin.

MMA Junkie indicates that Shields signed the deal on Monday, and she will compete in both boxing and MMA in 2021.

Shields will be doing one-off fights at lightweight (155-pounds) and not taking part in the 2021 season.

Regular season events and playoff matches air on ESPN+ and ESPN2. The Championship Event on New Year's Eve will air exclusively on ESPN2 and ESPN Deportes.

In recent years, Shields has discussed the possibility of competing in MMA - and doing crossover boxing matches with the likes of UFC champion Amanda Nunes and Bellator champ Cris Cyborg.

Several boxers in the last few years have taken part in MMA bouts, including Heather Hardy, Amanda Serrano and others.

Shields is still slated to face Marie Eve Dicaire in a junior middleweight unification in the first quarter of 2021.
