Thierry Henry has given Arsenal an injury scare ahead of Sunday's clash with Manchester United.
The Daily Express reports that Henry injured his calf during the Gunners' Tuesday training session.
Arsene Wenger must now wait for the results of a scan before deciding whether the former Barcelona forward will be available for Sunday's match at the Emirates.
Henry is currently at Arsenal on a short-term loan deal from New York Red Bulls and was rumoured to be in line for a start against United.
Arsenal are fifth in the Premier League.
