The Colorado Avalanche have elected to take centre Ryan O'Reilly to salary arbitration.
The club had until 5pm et on Sunday to file and has decided to bring the case before a mediator.
O'Reilly made $6.5 million last season in the second year of a back-end-loaded contract.
The deal arose out of an offer sheet O'Reilly signed with the Calgary Flames prior to the lockout-shortened 2012-13 NHL season. The Avalanche decided to match the offer instead of losing O'Reilly's services and as such must now make him a qualifying offer of $6.5 million to retain his rights.
O'Reilly is slated to become a restricted free agent on July 1. The other 29 NHL clubs are still eligible to sign O'Reilly to an offer-sheet between July 1 and July 5 despite the filing, a change that was made in the collective bargaining agreement signed in January, 2013.
The 23-year-old scored 28 goals and added 36 assists in 80 games with the Avalanche in 2013-14. Originally selected by the Avalanche in the second round (33rd overall) of the 2009 NHL Entry Draft, O'Reilly has scored 73 goals and 118 assists in 345 career games with the club.
An arbitration hearing between O'Reilly and the Avalanche would likely occur in late July.
