Sue Bird and Diana Taurasi shared an emotional jersey swap after what may have been the final matchup in their iconic WNBA careers

• Sue Bird and Diana Taurasi may have played the final matchup of their legendary WNBA careers.
• Bird's Storm lost Sunday's playoff contest in overtime to Taurasi and her Phoenix Mercury.
• The duo - who are best friends and former college teammates - exchanged jerseys after the game.

Two of the WNBA's greatest ever may have faced off for the final time.

Best friends and former college teammates Sue Bird and Diana Taurasi went head-to-head as the Seattle Storm hosted the Phoenix Mercury for a single-elimination playoff game Sunday night. When the Storm lost in overtime to end their 2021 campaign, reality set in that Bird - who is 40 years old - could be done for good.

"It's been amazing," Bird said, reflecting on her career to ESPN's Holly Rowe after the game. "I will take my time and make the right decision."

After conducting their on-court post-game press conference together - where Taurasi urged the crowd to chant "one more year" at Bird - the WNBA legends hugged, peeled off their uniforms, then posed while holding each other's jerseys.

Taurasi, the league's all-time scoring leader, hugged her best friend again before running off the court with her fellow five-time Olympic gold medalist's uniform in hand. Bird, who has long led the WNBA in career assists, jogged away in the opposite direction, presumably to her locker room for what could have been the final time.
