In the 2016–17 season, Dell made the Sharks' opening night roster as the team's backup goaltender to Martin Jones. On October 18, 2016, Dell made his NHL debut and won against the New York Islanders.[4] On February 28, 2018, Dell signed a two-year contract extension with the Sharks.[5]
On October 13, 2020, Dell signed a one-year $800,000 contract with the Toronto Maple Leafs as a free agent.[6] After attending the Maple Leafs training camp for the pandemic delayed 2020–21 season, Dell was included in the team's taxi squad. On January 18, 2021, Dell's brief tenure with the Maple Leafs ended as he was claimed off waivers by the New Jersey Devils.[7]
On July 28, 2021, Dell signed as a free agent to a one-year, $750,000 contract with the Buffalo Sabres.[8] On September 13, Buffalo announced that Dell will wear jersey no. 30, a move that upset many fans as the number had not been issued since Ryan Miller's departure from the team in 2014.[9]
On January 25, 2022, during a game against the Ottawa Senators, Dell delivered an unprovoked hit to forward Drake Batherson, causing an ankle injury; as a result, Batherson was ruled out for the 2022 NHL All-Star Game which he was supposed to attend.[10] The following day, Dell was suspended three games for the hit, officially ruled as interference.[11]
