London - Manu Tuilagi has recovered from an ankle injury and could form an exciting midfield partnership with Billy Twelvetrees in England's Six Nations match against Ireland in Dublin on Sunday.
The Samoa-born centre will resume full training on Tuesday after missing the 38-18 victory over Scotland at Twickenham on Saturday, when Twelvetrees deputised and performed impressively in a try-scoring debut.
With Tuilagi likely to start in his favoured outside-centre position, Twelvetrees and Brad Barritt appear to be fighting for the spot inside him.
"Manu brings a unique set of skills and attributes to the game and the team," England coach Stuart Lancaster said.
Lancaster said on Monday that No 8 Ben Morgan is struggling to recover from an ankle injury.
Ireland also won their first match in the Six Nations, beating Wales 30-22.
