Arsenal striker Thierry Henry faces another spell on the sidelines after suffering stomach and groin injuries in Wednesday's Champions League game against PSV Eindhoven.

The French international only came on as a second-half substitute after recovering from the foot and hamstring problems that have dogged him all season.

"My thinking was he was not ready to start the game because he got injured," Arsenal manager Arsene Wenger told the club's Web site. "Again now he is out for a few weeks. It is a different injury, his stomach muscle and his groin. It is a very difficult season for him."

Arsenal drew 1-1 with PSV at the Emirates Stadium to lose the first knockout-round tie 2-1 on aggregate.

They lost the League Cup final to Chelsea 10 days ago, were knocked out of the FA Cup by Blackburn Rovers last week, and lie fourth in the Premier League table, 20 points behind leaders Manchester United.
