Kevin McNaughton has cancelled out Yann Kermorgant's opener to leave the match all square at the break between Bolton Wanderers and Charlton Athletic at the Reebok Stadium.
The Addicks took the lead in the 11th minute when Rhoys Wiggins raided down the wing and lifted a cross into the penalty area for Kermorgant to fire home with his left foot.
Charlton should have doubled their lead minutes later when Cameron Stewart fired a ball into the box and it fell kindly at the feet of Lawrie Wilson, but he could only scoop his effort over the bar.
Bolton came back into the game as Chris Eagles for the ball on the edge of the area and beat two men before launching a shot at goal, which was well turned away by Ben Alnwick.
The Trotters got their equaliser right on the stroke of half time as McNaughton collected a cross on the right and cut inside and out before firing a right-footed shot into the top corner.
