On the Knicks' 2012-13 schedule, the location for their game against the Pistons on Jan. 17 is marked "TBD." According to the New York Daily News, that matchup will take place in London, likely at the O2 Arena.
The NBA has not yet released any details.
It wouldn't be the first NBA regular-season game played in London. In March 2011, the New Jersey Nets played two games against the Toronto Raptors at the O2 Arena, and they won twice.
