Charlton Athletic came from two goals behind to claim a 2-2 draw with Oxford United and secure a replay in the third round of the FA Cup.

The League Two side took the lead in the 13th minute when Scott Davies found Johnny Mullins, who beat a stranded Ben Hamer with a deflected shot.

Oxford doubled their lead just 11 minutes later thanks to a powerful strike from Davies which Hamer failed to keep out after getting a hand on the ball.

Despite improving slightly as the first half progressed, Charlton nearly found themselves 3-0 down before the break when Sean Rigg struck a long-range effort over the crossbar.

The hosts looked far more dangerous at the beginning of the second half and they were rewarded for their improvement when Michael Morrison pulled a goal back by heading in Jordan Crook's cross.

Charlton took control of the game as Oxford retreated but they were frustrated for long spells, with Johnnie Jackson heading a good chance wide in the closing stages of the game.

However, the hosts managed to force a replay when Yann Kermorgant found space inside the box to turn in a cross from Danny Green.
