The reason for the change is the Midlanders are competing in the Europa League on the preceding Thursday, with their opponents still to be determined for the away tie.
They will face either Crvena Zvezda, Celta Vigo, PAOK or Lille after finishing second in the overall table.
In terms of domestic form, Villa beat us 2-1 in the reverse fixture in December and currently sit a place above the Reds in the table, in third spot.
The latest raft of fixture alterations announced by the Premier League include the postponement of Manchester City's game against Crystal Palace.
For the same reason, the other Carabao Cup finalists, Arsenal, have seen their trip to Wolves switched to Wednesday 18 February.
