The midfielder limped out of Colombia's 1-0 win over Senegal that booked a World Cup last-16 clash with England.
Bayern Munich star James was therefore considered a doubt for the R16 game in Moscow.
Colombia confirmed in a statement that James has undergone a scan on the injury.
"Results showed that he has a minor edema without a fibrillar rupture in the right soleus," the FCF said.
James was the Golden Boot winner at Brazil 2014 as Colombia reached the quarter-finals.
Colombia is set to train in a behind-closed-doors session today.
