On February 1, 2010, Prust (along with Jokinen) were traded to the New York Rangers in exchange for Aleš Kotalík and Chris Higgins.[8] Following the conclusion of the 2009–10.season, the Rangers re-signed Prust to a two-year, $1.6 million contract on July 2.[9]
In the 2010–11 season, Prust, a fourth-line utility player and occasional enforcer, was one of only seven NHL players to score at least ten goals as well as engage in at least ten fights.[10] He was awarded the Steven McDonald Extra Effort Award at the end of the season, given to the Rangers player who "goes above and beyond the call of duty" as voted on by the fans.[11]
During the 2014 Eastern Conference Finals against his former team, the New York Rangers, Prust was suspended for two games following a first period hit on forward Derek Stepan in Game 3. Stepan suffered a broken jaw on the play and subsequently missed Game 4.[18]
On July 1, 2015, Prust was traded to the Vancouver Canucks for Zack Kassian and Vancouver's 5th round draft pick in the 2016 NHL Entry Draft.[19] Prust struggled with the Canucks, putting up the fewest points since his rookie campaign. On February 2, 2016, he was waived by the Canucks[20] and, subsequently, reassigned to the Canucks' AHL affiliate, the Utica Comets.[21] On March 10, he returned to his home in London, ON, and was taken off the roster due to an ankle injury.[22] After the Canucks opted not to re-sign him following season's end, Prust became an unrestricted free agent yet again on July 1, 2016.[23]
Due to his ankle injury, teams were unwilling to give Prust a contract, with concerns continuing to be raised over his foot speed and ankle itself.[24] Going unsigned for the duration of the summer, he agreed to a professional tryout (PTO) contract with the Toronto Maple Leafs on August 22, 2016.[25] Prust's main reason for signing the tryout was to fulfill his childhood dream of playing for the Maple Leafs, the team he grew up cheering for.[24] After an unremarkable training camp, along with stiff competition for role players on the Leafs roster, he was released by the team on October 11, 2016,[26] He then embarked on his first overseas stint in late November 2016 after signing with the Thomas Sabo Ice Tigers of the German top-flight Deutsche Eishockey Liga (DEL).[27] In the 2016–17 season, Prust added a needed physical presence to the Ice Tigers, contributing 8 points in 29 games with the team.[28]
Vying for another attempt at an NHL comeback, Prust signed a PTO contract to attend the Los Angeles Kings' training camp prior to the 2017–18 season.[29] After attending camp for 10 days, Prust, along with fellow wingerShane Harper, were the first to be released from their PTOs on September 25, 2017.[30]
Post-playing career
Although he did not formally announce his retirement from professional hockey, Prust signalled the conclusion of his 12-year playing career in joining his former major junior club, the London Knights, as a coach on November 29, 2017.[31]
On June 4, 2018, via Instagram, Prust announced that he had begun working at the London, Ontario based financial guidance firm Navigator Financial.[32] He likewise opened a local fitness centre known as "BP8 Fitness" in December 2023.[33]
Prust has an uncle who was a Broadway actor.[37] His interests outside of hockey include golf and watching baseball.[38]
Prust began dating French-Canadian TV host Maripier Morin in 2010.[39][40] On June 22, 2015, the couple got engaged, and married in 2017.[41] Morin had been a cast member on three seasons of the Canadian reality series Hockey Wives and is a popular host of her own talk show in Quebec, as well as starring in her first feature-length film.[42] It was announced in September 2019 that the couple had separated.[43]
In 2020 Prust's charitable foundation launched a campaign to raise money for families of sick children to find accommodations in London during the COVID-19 pandemic in Ontario.[44] Prust was an outspoken opponent of mandates and "vaccine passport" policies related to COVID-19 vaccines. Prust was criticized after, in an August 2021 Twitter exchange related to vaccines, he replied to a woman with a post declaring that he hoped she would be subjected to forced prostitution.[45] Prust apologized for this.[46] Prust had, for a time leading up to this, generated controversy for polarizing and combative Twitter exchanges on subjects such as racial relations and the 2020 United States presidential election (in which he was opposed to the candidacy of DemocratJoe Biden).[47]
