West Ham United are reportedly fearful that Jarrod Bowen may not be back from injury in time for their Europa League quarter-final tie with French giants Lyon.
The 25-year-old suffered a foot injury in the 1-0 defeat to Liverpool earlier this month and has missed the Hammers' last four games in all competitions.
David Moyes has already ruled Bowen out of action until after the international break, although the ex-Hull City man has not suffered any significant damage.
However, the Evening Standard now reports that West Ham are worried about Bowen potentially sustaining a small heel fracture which could rule him out of the clashes with Les Gones.
West Ham are set to welcome Lyon to the London Stadium for the first leg of their last-eight tie on April 7 before travelling to the Groupama Stadium on April 14.
Bowen has amassed 12 goals and 11 assists from 39 games in a West Ham shirt this term and missed out on an England call-up for March's friendlies due to his injury.
