Samuel Eto'o will now undergo his medical on Thursday ahead of his move from Inter to Anzhi Makhachkala.
The Cameroon international was expected to be at Rome's Villa Stuart centre at midday on Tuesday for the tests, but they have been postponed for 48 hours.
Despite the delay, the transfer is still expected to be completed with the final details set to be wrapped up over the next day or so.
Russian officials will be in Italy again today where they will hold further discussions with the Nerazzurri.
It's understood that Eto'o will be sold for close to €30m, with the player signing a three-year contract worth over €15m a campaign.
Eto'o is 30 and has been a massive success at Inter since he arrived from Barcelona in 2009, as part of the deal that saw Zlatan Ibrahimovic go in the other direction.
He won the treble in his first season with the Nerazzurri and has scored 53 goals in 101 games for the Beneamata.
