Lampard fit for FA Cup final
Julian Belletti has also responded well to treatment after picking up a thigh problem at Sunderland last Sunday.
Everton boss David Moyes meanwhile will have captain Phil Neville and winger Steven Pienaar available to him for the game at Wembley, which will be the Merseyside club's first final since their 1-0 FA Cup win against Manchester United in 1995.
Both Pienaar and Neville have been declared fit after sustaining minor hamstring problems in last weekend's final league win at Fulham.
As well as the glory of winning the oldest cup competition in the world - this year in it's 128th year - the winning club will receive £2m from the Football Association and the runner-up £1m.
