Southampton are investigating allegations goalkeeper Artur Boruc threw a water bottle into the crowd during their defeat by Tottenham Hotspur on Sunday, the club said in a statement.
The Poland international is alleged to have tossed the bottle into the crowd during the first half of Tottenham's 2-1 win that left Southampton 19th in the Premier League.
"The club takes such allegations extremely seriously and will deal with the matter in the appropriate manner," Southampton said in a statement.
