Sunderland boss Roy Keane doesn't expect Andrew Cole to make his debut in Saturday's trip to former club Manchester United.
The 35-year-old ex-England international joined the Black Cats on a one-year contract last week.
But, having not played since being released by Portsmouth at the end of last season, Keane claims his former Red Devils team-mate is still some way short of match fitness.
Cole scored 121 times in 275 appearances during seven years with United.
"I would have thought it would be too soon for Andy," said Keane.
"We're not going to be taking any silly chances. Andy will train and then there's an international break coming up after that.
"That will give any new players a chance to get up to speed. We can't expect miracles and Andy has a slight groin strain anyway."
Meanwhile, Sunderland have confirmed that unsettled winger Tobias Hysen has completed a switch to Swedish club IFK Gothenburg.
The 25-year-old has moved to his hometown club for an undisclosed fee after spending just one season on Wearside.
Hysen's final game for the Black Cats was against Burnley in the Championship towards the end of last season.
