Dallas have earned a 2-2 draw at Philadelphia Union in their MLS encounter.

A 97th minute equaliser from Blas Perez was enough to cancel out Aaron Wheeler's late goal for Union, who miss the chance to go top of the Eastern conference.

Sebastien Le Toux and Jack McInerney both missed early chances for Union, before centre-back Amobi Okugo headed into the bottom corner from a free kick.

The hosts were barely ahead for five minutes before Dallas levelled in similar fashion. Walker Zimmerman was on hand to head home Michel's delivery from wide.

Raymon Gaddis then had two efforts in quick succession saved by Raul Fernandez in the Dallas goal, as the sides went in level at half time.

Ten minutes into the second half Michel produced another good delivery, but this time Matt Hedges couldn't direct his header on target.

Union pushed forward as the match went on and eventually got their winner when substitute Wheeler headed in from close range after a neat move on the right.

That was not the end of the story, though, as yet another header, this time from Perez in the final minute of injury time, earned the visitors a point.
