While rumours of a possible trade between the Buffalo Sabres and Edmonton Oilers for Ryan Miller have been rampant over the last couple of days, there's one important obstacle that would prevent such a deal from going through.

TSN Hockey Insider Pierre LeBrun confirms that the Oilers are among the eight teams on the veteran netminder's no-trade list which his camp submitted to the Sabres in the summer.

Miller, who becomes an unrestricted free agent next July, has been the subject of trade speculation that's only been amplified with Buffalo's 1-6-1 start to the regular season.

This is not to say it’s impossible that Miller would waive it to go to one of those eight teams, but it certainly gives him control of the situation.

At this point, a source told ESPN.com that there have been no such discussions between the Sabres and Miller about any trade scenarios.
