Isabelle Harrison Bio
Isabelle Harrison is an American professional basketball player for the New York Liberty of the Women’s National Basketball Association (WNBA). She is the daughter of former National Football League (NFL) defensive end Dennis Harrison Jr. A power forward listed at 6 ft 3 in (1.91 m), Harrison has built a career in multiple professional leagues across the United States, Europe, and Asia since being selected in the 2015 WNBA draft.
Born in Nashville, Tennessee, Harrison developed into one of the top frontcourt players in the Southeastern Conference (SEC) during her college career at the University of Tennessee. She has represented clubs in Poland, South Korea, Italy, and the Czech Republic alongside her WNBA stops, and she also competes in Athletes Unlimited Pro Basketball.
Early Life and Background
Isabelle Harrison was born on September 27, 1993, in Nashville, Tennessee. She grew up in the same city and attended Hillsboro High School, where she developed into a highly recruited post player. Her athletic upbringing was shaped by her father, Dennis Harrison Jr., a former NFL defensive end whose professional football career provided a strong sports foundation in the family.
Her height and skill set allowed her to stand out as a high school prospect, drawing attention from major college programs. Harrison was rated among the top post players in her recruiting class and committed to the University of Tennessee, a program with a long tradition of developing frontcourt talent within the SEC.
At the high school level, Harrison was named a McDonald’s All-American, an honor that underscored her status as one of the top high school players in the country. She used her senior season to refine her game before making the transition to collegiate competition in Knoxville.
Path to Basketball
Harrison enrolled at the University of Tennessee in 2011 and quickly became a contributor for the Lady Volunteers. Playing in the SEC, one of the most competitive conferences in women’s college basketball, she developed against top-tier post players and earned recognition for her scoring, rebounding, and shot-blocking ability.
Her development accelerated during her junior and senior seasons. Harrison earned First-team All-SEC honors in 2014 and 2015, and she was named the SEC Tournament Most Valuable Player (MVP) in 2014, establishing herself as one of the conference’s premier frontcourt players.
During her senior year in February 2015, Harrison tore her anterior cruciate ligament (ACL) in a game against Kentucky, an injury that cut short her final college season. Despite the injury, she declared for the 2015 WNBA draft and was selected 12th overall in the first round by the Phoenix Mercury, becoming the 34th Lady Vol chosen in league history and the first since 2012.
Isabelle Harrison Career
Early Career (2015–2017)
After being drafted by the Phoenix Mercury in 2015, Harrison sat out her entire rookie year to recover from the torn ACL she suffered in college. She made her professional debut in 2016 and appeared in 26 games as a reserve, averaging 3.1 points and 1.8 rebounds per game. Her limited but encouraging first season showed glimpses of the post play that had made her a top draft pick.
Following her rookie campaign, Harrison began supplementing her WNBA schedule with overseas opportunities. She joined CCC Polkowice in Poland for the 2016–2017 season, gaining experience in European competition. In 2017, she was traded from the Mercury to the San Antonio Stars as part of a deal that sent Danielle Robinson to Phoenix, and she also played for Bucheon Hana 1Q in South Korea that winter.
San Antonio Stars / Las Vegas Aces Era (2017–2018)
Harrison’s time with the San Antonio Stars coincided with the franchise’s relocation to Las Vegas, where the team became the Las Vegas Aces. During this period, she continued to develop her role as a frontcourt contributor and gained valuable playing time in a retooling roster. Her physical presence and rebounding helped stabilize the team’s interior rotation.
Alongside her WNBA duties, Harrison played in Italy for Dike Napoli during the 2018–2019 season, expanding her international resume. The combination of WNBA and overseas schedules helped her build endurance and adapt to varied styles of play across multiple leagues.
Dallas Wings Era (2019–2022)
On May 16, 2019, Harrison was traded to the Dallas Wings, where she would spend the next three seasons. She became a consistent presence in the Wings’ frontcourt, contributing scoring, rebounding, and veteran leadership. During this stretch, she also spent time overseas with USK Praha in the Czech Republic and Virtus Eirene Ragusa in Italy, continuing her pattern of year-round professional play.
Her tenure in Dallas represented her longest and most stable WNBA stretch to that point. Harrison grew into a reliable rotation player, and her experience in multiple basketball systems made her a versatile asset for the Wings’ coaching staff.
Chicago Sky Era (2023–2024)
Harrison signed with the Chicago Sky on February 2, 2023, during WNBA free agency. Her first season with the Sky was disrupted by a torn left meniscus that required surgery, causing her to miss the entire 2023 campaign. She worked through her rehabilitation and returned to action the following season, providing frontcourt depth for Chicago.
After her time with the Sky, Harrison returned overseas to USK Praha for the 2024 season, reuniting with the Czech club she had previously represented. The international experience allowed her to maintain her conditioning and game shape during the WNBA offseason.
New York Liberty Era (2025–Present)
On February 21, 2025, Harrison signed with the New York Liberty in WNBA open free agency, joining a championship-contending roster. The move paired her with a veteran core and gave her an opportunity to compete at the highest level of the league. Her size and experience fit the Liberty’s frontcourt rotation.
Harrison has also remained active in Athletes Unlimited Pro Basketball, where she has competed since the league’s early seasons. During the 2025 Athletes Unlimited season, she finished eighth on the final leaderboard, ranking among the league leaders in scoring and rebounding. She recorded multiple 20-point performances and helped set a league record for single-week win points. In August 2025, she signed to return to Athletes Unlimited for her fifth season, competing again in Nashville.
