Christian Ribeiro’s first-half strike cancelled out Tariqe Fosu’s opener as Charlton drew 1-1 against Oxford.

Fosu’s 18th-minute goal had given Charlton, who were well on top, an early lead.

The result leaves the Addicks in the play-off places, eight points away from second-placed Wigan with a game in hand.

Karl Robinson made two changes to the side that beat Doncaster on Saturday, with Ben Reeves replacing Billy Clarke for his first league start, while Naby Sarr came in for Ezri Konsa.

Oxford fired the first warning shot when Jack Payne’s cross found Josh Ruffels, who volleyed wide.

And the visitors had their first attack of the evening as Ricky Holmes was inches away from connecting with Josh Magennis’ cross.

Fosu was Charlton’s biggest threat in the first-half and should have given his team the lead in the 17th minute after finding space in the box. However, the in-form winger failed to keep his effort on target.

But he made amends just a minute later when he put the Addicks in front to score his sixth goal in four games. The former Reading man beat U’s goalkeeper Simon Eastwood to a loose ball and smashed it into an empty net.

And Charlton nearly doubled their advantage just moments after the opener, but Holmes could not keep his volley down.

Oxford’s equaliser came in the 35th minute thanks to Ribeiro’s volley. Chris Solly’s clearing header fell to the full-back whose strike beat Ben Amos.

And Charlton rode their luck for the rest of the half as Oxford cranked up the pressure. Ruffles saw a 20-yard strike curl off target, before Wes Thomas directed his shot wide from a tight angle.

And the best chance to take the lead came just before the break when Jake Forster-Caskey’s excellent goal-line clearance denied Ricardinho.

There was almost a third Ricky Holmes wonder goal of the season to celebrate when his long-range volley flew inches over the bar.

The Addicks threatened again as Magennis’ cut-back picked out Holmes, whose strike was well blocked.

Oxford responded to the Addicks’ early second-half chances when Thomas’ header was tipped over by Amos on the hour mark.

Magennis had his first sniff of the game after directing his header wide in the 71st minute - he should have hit the target.

And Fosu’s confidence was on show when he fired wide in the box - passing to an unmarked Clarke would have been the better option.

Karlan Ahearne-Grant could have won it for Charlton late on, but his effort was well wide of Eastwood’s goal.
