Tammy Abraham has flown to Barcelona to get more advice on his ankle injury, according to Chelsea manager Frank Lampard.
The striker missed the Blues' 2-2 draw away to Bournemouth on Saturday evening, with Olivier Giroud replacing him in the starting lineup.
His issue started when he slid into the advertising boards during the match against Arsenal and has since played with pain and sometimes forced to take painkillers to see him through matches.
"He went to Barcelona to have a look at his ankle with another pair of eyes on it but I’ve got no update. I’m hoping it’s not a long-term injury but at the same time I can’t say he’ll be back for Tuesday," he said after the match.
Abraham has been phenomenal for the Blues in the Premier League with 13 goals, even though the goals seem to have dried up in recent games.
Chelsea struggled against Eddie Howe's side, with Marcos Alonso coming to their rescue with two goals, the equalizer coming five minutes from time.
Lampard complained lamented on his side's inability to finish off games, especially having taken the lead in the first half.
They next play Everton in the Premier League, but not before an FA Cup tie against league leaders Liverpool on Tuesday night.
