Chelsea striker Tammy Abraham has travelled to Spain to see a specialist in an effort to finally solve the riddle on his ankle problem.
Abraham has struggled with an ankle injury since he collided with the advertising hoardings in the draw against Arsenal in January at Stamford Bridge.
The injury saw the 22 year old striker miss the game against Manchester United and a brief substitute appearance against Bayern Munich saw the problem flare up again.
Lampard said: “He went abroad, he went to Barcelona to have a look at his ankle, get some other eyes on it.
“I’m hoping it’s not a long-term injury but at the same time I cannot tell you he will be ready for Tuesday or Sunday.”
Abraham is now expected to miss Tuesday’s FA Cup fifth round tie at home to Liverpool.
