NEW YORK (

TheStreet

) -- Stock futures pointed to a much weaker open Friday as eurozone contagion fears heightened and markets focused on Portugal's sovereign debt situation.

S&P 500

U.S. markets were closed on Thursday for the Thanksgiving holiday. On Wednesday, stocks rallied on a sharp drop in initial jobless claims and improved consumer sentiment.

Contagion concerns hit the euro, which fell to $1.3218 from $1.3355.

Global stocks

fell sharply as markets questioned whether the European Union and the International Monetary Fund will be able to support other debt-logged eurozone countries if they ask for an aid plan similar to Ireland's.

The market focused on

Portugal

despite repeated assurance from Prime Minister Jose Socrates that the country was not intending to seek bailout funds.
