A native of
Czechoslovakia, Lang began his career in the
Czechoslovak Extraliga as an eighteen-year-old with
HC Litvínov. After scoring 15 points in 32 games in 1989–90, his second season with HC Litvínov, he was drafted 133rd overall by the
Los Angeles Kings in the
1990 NHL entry draft. Lang returned to play another two seasons in the Extraliga before debuting with the Kings in
1992–93. He played the majority of his first two seasons in the
International Hockey League (IHL) with the Kings' minor league affiliate, the
Phoenix Roadrunners. Due to the lockout-shortened
1994–95 season, Lang returned to HC Litvínov (now of the
Czech Extraliga) for 16 games, scoring 23 points. When NHL play resumed, he landed a full-time roster spot with the Kings. He tallied 22 points in 68 games in
1995–96 before returning to the Czech Extraliga to play for
Sparta Praha. After a brief hiatus from the NHL, Lang returned after one season in
Europe, joining the
Pittsburgh Penguins as a free agent on September 2, 1997. He was subsequently bounced back and forth between the Penguins and
Boston Bruins for a couple of months before he stuck with the Penguins. Lang remained with the Penguins, joining fellow Czech
Jaromír Jágr and increasing his points total in each of his first four seasons with the team. In
2000–01, he scored a career-high 32 goals, 48 assists and 80 points in 82 games. That season, the Penguins reached the
Eastern Conference Finals, but were defeated in five games by the
New Jersey Devils. Lang added eight points in 16 playoff games. After the
2001–02 season, Lang became an
unrestricted free agent and signed with the
Washington Capitals. During the
2003–04 season, Lang was enjoying another career year and recorded his first career
hat-trick on November 12, 2003. He was leading the NHL in scoring when he was traded to the
Stanley Cup-contending
Detroit Red Wings for prospect
Tomáš Fleischmann, a first-round draft pick (
Mike Green) in
2004 and a fourth-round pick in
2006. This marked the first time in NHL history that a player was traded while leading the NHL in points. Shortly after the trade, he was sidelined with a broken rib on March 8. Missing 13 games, he surrendered the NHL scoring lead to the
Tampa Bay Lightning's
Martin St. Louis and finished with 79 points in 69 games, one point shy of his career-high set in 2000–01 and ninth overall in the League. (Lang's points-per-game of 1.14 was identical to St. Louis'.) Lang returned to the Red Wings in time for the
2004 playoffs, but the team was eliminated by the
Calgary Flames in the second round. He recorded a career-high nine points in 12 playoff games. In addition to Lang's ninth-place finish in NHL scoring, he had participated in his first
NHL All-Star in
2004 and was also awarded the
Golden Hockey Stick as the top Czech hockey player at the end of the season. Lang remained with the Red Wings until the end of the
2006–07 season, but his production dipped each of his remaining campaign in Detroit. Before signing a two-year contract with the
Chicago Blackhawks as an unrestricted free agent in the off-season, Lang embarked on another playoff run with the Red Wings in
2007, but they were halted by the eventual Stanley Cup champions
Anaheim Ducks in the semifinals. Lang recorded eight points in 18 playoff games. In Chicago, Lang recorded 54 points playing behind rookie standouts
Jonathan Toews and
Patrick Kane; Lang finished fourth in team scoring. After just one season with the Blackhawks, he was traded to the
Montreal Canadiens for a second-round draft pick in
2010 (previously acquired from the
Toronto Maple Leafs) on September 12, 2008. Lang recorded a natural hat-trick, the second three-goal effort of his career, in his first season with the Canadiens, against the
New York Rangers on January 7, 2009, in a 6–3 win. He scored his three goals on the
power play, even-strength and
short-handed in an empty net. Having played 50 straight games for the Canadiens, leading them in goal scoring, power play points and second on the team in overall points, Lang suffered an achilles tendon injury, sidelining him for the remainder of the regular season. On September 29, 2009, Lang was signed by the
Phoenix Coyotes to a one-year contract, just days before the start of the
2009–10 season. During the season, Lang recorded 29 points in 64 regular season games while missing the last 17 games of the regular season due to a lower-body injury. His offensive contribution and veteran leadership helped lead the Coyotes to their first playoff berth since the 2001–02 season. The Coyotes were defeated by the Red Wings in seven games in the first round of the
2010 Stanley Cup playoffs. Lang played in four of the seven games, recording one assist. ==International play==
