On March 31, 2010, the Ottawa Senators signed Gryba to a two-year, entry-level contract.[2] On February 16, 2013, he made his NHL debut, playing for Ottawa in Toronto against the Toronto Maple Leafs.[3]
Gryba earned his first career NHL point, an assist, against the New York Islanders on February 19, 2013, and scored his first career NHL goal against the Tampa Bay Lightning on March 23, 2013.[4]
On May 2, 2013, in his first Stanley Cup playoff game against the Montreal Canadiens, Gryba delivered a questionable, open-ice hit to Canadiens' forward Lars Eller as Eller received a pass from Raphael Diaz. The hit caused Eller's face to strike the ice, leaving him bleeding and motionless on the ice and later carried off via stretcher. Though there was some question as to whether or not the hit was illegal,[5][6] Gryba was subsequently suspended for two games when the NHL deemed that Eller's head had been the principal point of contact.[7]
On June 26, 2014, Gryba signed a two-year contract extension with the Senators, valued at $2.5 million.[8]
After appearing in 53 games for the club, the Oilers chose not to re-sign Gryba, making him an unrestricted free agent. However, Gryba signed a one-year, two-way contract on October 12, 2016, after attending the team's camp on a professional tryout.[10] On December 31, 2017, Gryba cleared waivers and was assigned to the Oilers' American Hockey League (AHL) affiliate, the Bakersfield Condors.[11]
On June 21, 2018, the Oilers placed Gryba on unconditional waivers for the purpose of a buyout.[12]
New Jersey Devils
On July 1, 2018, the opening day of free agency, Gryba was signed by the New Jersey Devils on a one-year, two-way $700,000 contract.[13]
Gryba's father Shawn is a retired teacher, and his mother Catherine was an executive for the City of Saskatoon. Gryba attended St. Joseph High School. He became engaged to Cate Eckhardt in August 2015[15] and the two married in the summer of 2016.[16] Gryba is also an avid hunter and fisherman who co-owns a company called Capital Waterfowling, and has a TV show called Grilling With Gryba.
