The midfield playmaker limped off 40 minutes into Denmark's 2-1 friendly win at home to Norway on Friday following a late tackle by Vegard Forren.
Spurs feared the 21-year-old had ruptured ankle ligaments, but scans revealed just a sprain.
"Following an MRI scan on Monday it has been determined that Christian Eriksen suffered a sprain of the lateral ankle ligaments playing for Denmark against Norway on Friday," a Tottenham statement said. "The scan showed no sign of ruptured ligaments which will result in a shorter period of recovery for the attacking midfielder."
Although Spurs haven't specified a time-frame for Eriksen's recovery, if all goes well the £11.5m pre-season signing from Dutch giants Ajax could be back in action against Liverpool at White Hart Lane on 15 December.
Eriksen was man-of-the-match on his Spurs debut against Norwich City and scored in the following fixture against Tromso in the UEFA Europa League.
A dip in form saw him lose his place to Lewis Holtby but Eriksen was in the starting XI for Spurs' last game against Newcastle United.
Holtby, Erik Lamela, Gylfi Sigurdsson and Harry Kane can all play in Eriksen's position while Spurs manager Andre Villas-Boas could also opt to change formation and play two strikers rather than a lone forward up front.
