Arsenal striker Thierry Henry is likely to miss the Premier League match against leaders Chelsea on Wednesday due to a groin injury, manager Arsene Wenger said on Monday.
The Frenchman, who is the league's leading scorer with 25 goals this season, sat out Saturday's 3-0 FA Cup semi-final win over Blackburn Rovers.
"In my opinion, Thierry will miss the game," Wenger told Arsenal's website.
"We will miss him as he's an exceptional player. But we can do more collectively and try to compensate."
Wenger said he would make a late decision about whether to include defender Sol Campbell from the start. The England international has not played since February 1 due to an ankle injury.
Swedish midfielder Freddie Ljungberg looks likely to miss the game at Stamford Bridge after suffering a recurrence of his long-standing hip problem.
Chelsea lead champions Arsenal by 11 points with six games to play and if they win Wednesday's match at Stamford Bridge, they will need only one more victory to secure their first league title for 50 years.
