Clarke MacArthur failed his medical on the opening day of Ottawa Senators training camp Thursday.
His future in the game is – once again – in doubt.
MacArthur has sat out the majority of the past two seasons with concussion problems, but did return in the final week of the 2016-17 regular season before having a major impact on the Senators run to the Stanley Cup final.
While there were concerns throughout the summer about MacArthur’s status for the 2017-18 season, they weren’t confirmed until Thursday’s tests.
“Right now, we don’t know much, but he won’t be part of camp,” said Senators general manager Pierre Dorion.
