Ipswich Town lead at Charlton Athletic at the break through DJ Campbell after he atoned for an early penalty miss.

The visitors spurned a gilt-edged chance to go ahead from the spot following Emmanuel Frimpong's foul on Lee Martin.

Campbell stepped up but failed to the find the target with a wayward penalty.

Aaron Cresswell threatened for Ipswich throughout the first 45 minutes, while Campbell was denied once again by a smart save from Ben Hamer.

Mick McCarthy's side finally took the lead ten minutes before the interval when Campbell reacted quickest in a crowded box after Daryl Murphy's initial cutback.

Charlton struggled to create chances in the opening period but came close to a goal through Dale Stephens, who watched his fierce free kick come back off the post.

Just moments before half-time Ipswich doubled their advantage when Murphy tucked home a rebound from close range.
