The Lancashire derby between Burnley and Bolton Wanderers is all-square at the interval, after both sides failed to make the breakthrough.
An early slip from Burnley keeper Tom Heaton almost gave the hosts a dream start, but Kieran Trippier cleared the ball before any Bolton players could tap home.
Heaton made amends moments later after pulling off a relatively routine save from Lee Chung-Yong's strike, with the South Korean cutting inside before getting his shot away.
It was Lee who again came close to giving the Trotters the lead with 10 minutes on the clock, following his deflected strike which came back off the crossbar to keep the scores level.
Burnley had to soak up the early pressure before finally coming close themselves. Scott Arfield found the ball at his feet just outside the opposition area, but the winger could not direct his effort on goal.
Both sides pushed for a goal late in the first half, but neither could find the breakthrough to leave the scores level at the interval.
