2008-09: Marek Tvrdon appeared in just one game for HK Nitra U20 in the Slovakian junior league and did not register a point.
2009-10: Tvrdon played a full season with HK Nitra U20 and was dominant over 45 games. He tallied 25 goals and 31 assists to go along with 90 PIMS.
2010-11: Tvrdon made the jump to North America and the WHL’s Vancouver Giants for his draft year. He stormed out of the gates with 11 points (6 goals and 5 assists) in 12 games before suffering a dislocated shoulder that knocked him out for the remainder of the season.
2011-12: Tvrdon was the second-leading scorer for the Vancouver Giants in his second WHL season and skated for Slovakia in the 2012 U20 World Junior Championship. He scored 31 goals with 43 assists and was plus-one with 62 penalty minutes in 60 games for the Giants. Vancouver finished second in the B.C. Division. Tvrdon scored 3 goals with 3 assists and was minus-four; skating in all six games of Vancouver's first round series with Spokane. He was Slovakia's second-leading goal scorer, scoring 3 goals, and had 1 assist; finishing minus-four with 14 penalty minutes in six games. Slovakia finished sixth in the 10-team tournament.
2012-13: Tvrdon signed a three-year entry-level contract with the Red Wings in July 2012 and was off to a fast start for the WHL's Vancouver Giants before being diagnosed with a blood clot in his arm that forced him to stop playing. In 18 games he scored 8 goals with 14 assists and was +2 with 16 penalty minutes. He was able to practice with Detroit AHL affiliate Grand Rapids during the Calder Cup playoffs but did not appear in any games.
Tvrdon has all the tools and ability to be a top six NHL power forward. He has size that he uses well and he isn’t afraid of physical play or getting his hands dirty. He boasts excellent speed, soft hands, great instincts and a scorer’s touch. The fact that his effort level can be inconsistent is a concern, but he could be something special if he develops.
Tvrdon's development has been significantly slowed by injuries, but that will not stop him from taking the next step in his career and moving up to the AHL's Grand Rapids Griffins in 2013-14. If Tvrdon can stay healthy then he could be a surprise contributor for the Griffins.
