at 114. Following an injury to San Jose defenceman Douglas Murray, Joslin made his National Hockey League debut January 3, 2009, in a game against the New York Islanders. He continued to split time between the NHL and the AHL, and was named to the AHL All-Star Game. At the AHL All-Star Skills Competition Joslin won the Hardest Shot Contest shooting a puck at 98.6 mph and also finished second in the Puck Control Relay. He finished the year playing in 12 NHL games, without scoring, and 63 AHL games registering 11 goals and 30 points. The 11 goals tied a Worcester franchise record for defenceman. For the 2009–10 season, Joslin again split time between the NHL and AHL. He registered his first NHL point, an assist, against the Chicago Blackhawks. It began a career high three game assist streak, which were his only points in 24 NHL games for the year. In the AHL playoffs Joslin scored 4 goals in 11 games tying for the team lead and leading the league for defencemen. In 2010–11 he remained in the NHL for the entire season and scored his first NHL goal on Andrew Raycroft of the Dallas Stars on December 13, 2010. Although he was regularly a healthy scratch playing in only 17 for San Jose before a February 18, 2011 trade sent him to the Carolina Hurricanes in exchange for future considerations. Following some injuries to Hurricanes' defenceman, Joslin received increased ice time including time on the power play. After joining Carolina Joslin scored 5 points in 17 games. During the off season Joslin became a restricted free agent. The Hurricanes sent him a qualifying offer, but could not come to terms and Joslin filed for salary arbitration. The following day the two sides agreed on a two-year contract. During the first season of his new contract Joslin fell behind other defenceman on the depth chart and was regular healthy scratch, only playing in 14 of the first 41 games. With the belief that Carolina would trade a defenceman head coach Kirk Muller played Joslin at left wing in order to get him back in the line-up and be ready if a trade occurred. After the trade deadline passed, with no trades made, Joslin continued to play wing including his 100th career NHL game. He finished the season playing in an NHL career high 44 games scoring 2 goals
