Seven-time winner Stephen Hendry, who defeated Joe Perry in the first round, might quit snooker this year after revealing he will weigh up his future in the summer - even if he carries off another world title.
Hendry has not triumphed in Sheffield since beating Mark Williams in the 1999 final.
By his own admission he ‘got out of jail’ against Perry yesterday. Defeat would have knocked him out of the top 16 for the first time since 1988.
Hendry said: ‘If I win this thing I might still contemplate retirement. I've got a big decision to make at the end of the season.’
China's Ding Junhui, who lives in Sheffield during the season, clinched his place in the second round with a 10-2 victory at the expense of Scotland's Jamie Burnett.
Peter Ebdon, the 2002 champion, is making his 20th consecutive appearance at the Crucible, having made his debut in 1992.
He led 4-2 against Stuart Bingham but will resume tonight trailing 5-4.
Stephen Maguire, the world number seven from Glasgow, crashed out in a late-night finish as he suffered a 10-9 defeat against qualifier Barry Hawkins.
Hawkins had lost in the first round in each of the last five years, and was thrilled to finally register a victory at the Crucible.
The Dartford man said: ‘It feels like I've won the World Championship.’
