Manchester United defender Rio Ferdinand suffered a knee injury in their FA Cup defeat to Swansea City.

Ferdinand, 35, had been making his first appearance since December 10 when he was forced off after 76 minutes of the third-round contest at Old Trafford.

There had been fears the former England international could face a longer lay-off but it is understood scans have revealed heavy bruising rather than any ligament damage.

It is thought Ferdinand is likely to be out for 10-14 days.
