EX-SUNDERLAND footballer Chris Black has gone missing from new club Doncaster Rovers.
The South Yorkshire side are puzzled as to where the 21-year-old midfielder is, after he failed to show for training.
Black has not been seen since Saturday, when Doncaster played a 0-0 draw with Oxford United in Division Three.
Rovers' boss Dave Penney said he was "mystified" as to where the Ashington-born player might be. However, it is thought he is safe.
Penney said: "It's a mystery because we felt he had done well in his first game and he gave no indication of any problems."
Black joined Rovers on a free transfer just before deadline day last month, on a deal which lasts until the end of the current season.
He played two first-team games for Sunderland towards the end of last season, as the club was relegated from the Premier League.
It is believed he has been in touch with officials at the Stadium of Light.
A Doncaster spokesman said: "Rovers have had contact with Sunderland and they have discussed Chris with Dave Penney.
"The club are not in a position to make any other statement at this time, other than Chris is quite safe."
Sunderland AFC declined to comment because Black is no longer a Black Cats' player.
