Ryan, 32, has been in and out of the lineup to start the 2019-20 season. A healthy scratch in five games, he recorded four points on a goal and three assists in 16 games played. His lone score came on opening night against the Toronto Maple Leafs and all four points pre-date Oct. 24 and has just one assist in his last 12 games played.
The second-overall pick in 2005, Ryan did not play in Ottawa's win over Detroit on Tuesday. According to head coach D.J. Smith, he left practice early the day before because he did not feel well.
General manager Pierre Dorian released a statement following the news on Wednesday saying, “Bobby is an important member of the Ottawa Senators family and he has our full support as he tends to this matter.”
In seven seasons with Ottawa, he has netted 103 goals and 159 assists in 447 games. Prior to his trade to the Senators in 2013, he saw his best seasons in Anaheim, hitting the 30-goal plateau for four consecutive seasons spanning 2008-09 to 2011-12; the only 30-goal seasons of his 13-year career.
The press release stated there will be no further comment regarding why Ryan is away from the team.
