Wolf's first full season of professional hockey was the 2007–08 season. He appeared in 46 games for ETC Crimmitschau in the 2nd Bundesliga, the second level of German hockey. Following a 9-point season, Wolf returned to ETC Crimmitschau for the 2008–09 season, where he scored 8 points and recorded 120 penalty minutes in 36 games. Wolf was a member of the German national junior team at the 2009 World Junior Ice Hockey Championships. He scored one goal in the tournament, against Canada, and recorded 53 penalty minutes in six games. In 2009–10, Wolf moved up to the Deutsche Eishockey Liga and joined the Hannover Scorpions. He played two seasons with Hannover before moving to the Hamburg Freezers in 2011. He earned a place on Hamburg's top line and enjoyed a dramatic increase in his offensive production; Wolf scored 35 points in 46 games in 2011–12 after recording only 6 in 51 games the year before. He also led the DEL with 167 penalty minutes. The National Hockey League's Toronto Maple Leafs offered Wolf a try-out at their 2012 summer camp but he failed to stick with the team. Wolf returned to Hamburg for the 2012–13 season where he scored a career high 17 goals and added 19 assists. He improved to 40 points the following season, and again led the DEL in penalties with 152 minutes. Wolf also played with the German national team in that country's failed attempt to qualify for the 2014 Winter Olympics. Following the 2013–14 DEL season, Wolf left Germany intending to try to make the NHL. He signed a one-year, two-way contract with the Calgary Flames. The Flames assigned him to their American Hockey League affiliate, the Adirondack Flames to begin the 2014–15 season. He scored 12 goals and added 9 assists in his first 35 games with Adirondack before earning his first recall to Calgary on 26 January 2015. Wolf made his NHL debut on 31 January, a 4–2 victory over the Edmonton Oilers. He suffered a laceration to this thigh during the game and missed the following three games due to the injury. Wolf turned down offers to remain in North America and returned to Germany for the 2015-16 season, again signing with the Hamburg Freezers. Following the 2015-16 campaign, he was traded to fellow DEL side Adler Mannheim in exchange for Martin Buchwieser. Wolf signed a seven-year deal with the Adler organization.
