Jeff Cornwall Bio
Jeff Cornwall (born May 28, 1991, in Coquitlam, British Columbia) is a Canadian professional box lacrosse player. He competes in the National Lacrosse League, where he is recognized as a defensive player who shoots left-handed. Cornwall has built his career through multiple NLL franchises and is also an international competitor, having represented Canada at the 2024 World Lacrosse Box Championships in Utica, where his team earned gold. Standing 6 ft 2 in (188 cm) and competing at 210 lb (95 kg), he has developed into a steady presence on the back end of the floor.
Early Life and Background
Jeff Cornwall was born on May 28, 1991, and grew up in Coquitlam, British Columbia, a city in Metro Vancouver with a deep tradition of box lacrosse. The Lower Mainland is widely considered one of the heartlands of the sport in Canada, and Cornwall was raised within that competitive environment. From a young age, he was immersed in the local box lacrosse culture that helped shape his defensive approach to the game.
He is the brother of Travis Cornwall, who has also pursued a professional box lacrosse career and plays for the Las Vegas Desert Dogs. Growing up alongside a sibling who followed the same path provided Jeff with a built-in training partner and an early understanding of the demands required to reach the professional level. The Cornwall family has continued to be associated with the sport at its highest levels.
Path to Professional Lacrosse
Cornwall developed through the British Columbia youth and minor lacrosse system, where his size and left-handed shot drew the attention of National Lacrosse League scouts. He was selected 15th overall in the second round of the 2011 NLL Entry Draft by the Buffalo Bandits, a clear signal that he was viewed as an early career prospect. Although he was drafted in 2011, his professional career officially began in 2012, when he appeared in his first NLL contests. The path from Coquitlam’s box lacrosse rinks to the NLL floor reflected years of development against some of the most competitive amateur players in the country.
Jeff Cornwall Career
Early Career (2012–2013)
Jeff Cornwall began his National Lacrosse League career with the Buffalo Bandits during the 2012 season. In his rookie year, he appeared in five games with Buffalo, an introduction that gave him a feel for the pace and physicality of professional box lacrosse. The Bandits ultimately moved him, trading him to the Edmonton Rush in exchange for two second-round picks in the 2012 Entry Draft, Jordan Critch and Carter Bender.
The trade to Edmonton opened the door to a larger role with the Rush, where Cornwall had the opportunity to develop his defensive game in a stable environment. His time with the organization allowed him to gain valuable experience and refine the skills that would shape his career. That early chapter also marked his transition from a draft pick to a consistent NLL contributor.
Buffalo, Edmonton and Vancouver Era (2013–2018)
Cornwall became a regular contributor with the Vancouver Stealth, a franchise with which he built the longest stretch of his early career. Playing in his home province gave him a familiar stage on which to perform, and he became a reliable presence on the Stealth defensive unit. His role with Vancouver allowed him to face top NLL offensive players on a nightly basis and to develop into a steady two-way defender.
After his time with the Stealth, Cornwall joined the Calgary Roughnecks, where he continued his NLL career in another competitive Western Canadian market. The Roughnecks’ system emphasized transition defense and disciplined positioning, and Cornwall fit comfortably into that approach. His stops with both Vancouver and Calgary established him as a respected defensive player in the league.
New York, Saskatchewan and Las Vegas Era (2019–2022)
In 2019, Cornwall was selected by the New York Riptide in the league’s Expansion Draft, briefly linking him to the league’s newest franchise. However, New York quickly traded him back to the Rush, who had relocated to Saskatchewan, in exchange for the 10th overall pick in the 2019 draft, used to select Tyson Bomberry. The move returned him to a familiar organization where he had already developed strong relationships with coaches and teammates.
During the 2022 Expansion Draft, he was selected by the Las Vegas Desert Dogs, only to be traded to the Calgary Roughnecks for Marshal King and an 18th overall pick in the 2022 Entry Draft, used on Austin Hasen. The back-to-back expansion activity illustrated how the league valued him as a roster piece. Despite the moves, Cornwall remained a steady defensive contributor.
Vancouver Warriors Era (2023–Present)
Cornwall returned to the Vancouver Warriors organization, where he currently serves as a defensive presence on the NLL roster. The Vancouver Warriors, formerly known as the Stealth, are a franchise deeply tied to the Lower Mainland lacrosse community. Playing in his home market has allowed Cornwall to take on a leadership role among the team’s defensive unit.
With Vancouver, he has continued to log regular minutes and contribute to the team’s defensive structure. His familiarity with the Warriors’ system and his local roots have made him a steady veteran presence. The 2025 season is expected to continue his role within the team’s back end.
Driving Style and Strengths
Cornwall is recognized primarily for his defensive positioning, reach, and physical presence. Standing 6 ft 2 in and weighing 210 lb, he combines size with a left-handed shot that makes him effective in transition. His calm decision-making and experience in high-pressure box lacrosse environments have helped him remain a reliable contributor across multiple organizations.
Notable Events and Milestones
One of the most significant milestones in Cornwall’s career came in 2024, when he represented Canada at the World Lacrosse Box Championships in Utica. Canada’s men’s box lacrosse team won the tournament, earning Cornwall an international gold medal. He has also appeared in NLL All-Star caliber matchups, though his primary recognition has come through his durability and consistency across rosters.

His veteran presence gives the team stability on defense and during transition play.
Throughout the early portion of the 2025 NLL season, Cornwall has been a steady presence in the Warriors’ lineup, providing the team with reliable minutes against top opposing offensive units.
