This summer, however, Great Britain got the commitment from Gordon for which they had been hoping.
"I'm really disappointed," added Gordon. "The British medical staff and management have been in touch with the Pistons over the past few weeks - unfortunately, I just won't be ready to play come August.
"I am really looking forward to playing next year and will follow the team's success this summer. It would have been great to play with Luol [Deng] this summer - it will just have to wait until next year."
Finch is expected to name his training squad for the eight-game qualifying campaign, which starts with a trip to Hungary on 2 August, this week.
Great Britain performance director Chris Spice admitted to BBC Sport at the weekend there were doubts over Gordon's participation.
Freeland, one of Britain's biggest successes of the past two summers, will also be missed.
With veteran centre Andrew Betts and Freeland's Malaga team-mate Robert Archibald both opting to rest this summer, Great Britain could be short of experienced height.
As a result, Finch is likely to be forced to include inexperienced players from the Futures squad around his remaining high-profile veterans such as Deng and Pops Mensah-Bonsu.
"It will be a great opportunity for some of the younger players to step up to the mark and stake a claim for a regular place," stated Finch. "Players like Justin Robinson, Matthew Bryan-Amaning and Ashley Hamilton all performed well for the GB Futures."
Also likely to feature is Dan Clark, who made last season's EuroBasket squad without getting to play in Poland.
With the 2012 Olympics approaching, Great Britain need to qualify for the 2011 EuroBasket finals in Lithuania to prove themselves worthy of a host's spot in London
World governing body Fiba recently stated that Great Britain must provide a lasting legacy for basketball beyond the 2012 Olympics as well as proving themselves competitive.
