The sides both find themselves fighting around the top end of the Western Conference standings in third and fourth spots respectively, with the hosts two points better off than their opponents.
Match preview
Austin FC have enjoyed a strong start o the MLS season on the whole, having, thus far, established themselves in the playoff places with eight victories and 27 points from their opening 15 matches.
They had to battle through a tough spell recently, though, as a five-game span produced just four points with a win over Los Angeles FC firstly followed by a draw against Orlando City.
Josh Wolff's side were then brushed aside by Los Angeles Galaxy, eventually falling to a 4-1 defeat despite Diego Fagundez giving them a lead in the second half, as Javier Hernandez and Efrain Alvarez hit goals either side of a Dejan Joveljic double for the Galaxy.
Looking to bounce back to form after that slight dip in form, Austin travelled to take on CF Montreal last time out, and their hopes took a major hit as Daniel Pereira was sent off on the stroke of half time, only for Maximiliano Urruti to hit the only goal of the game after the hour mark to seal all three points.
With that win taking them to third place, above state rivals and Sunday's opponents Dallas, they will hope to further strengthen their place at the top end of the Western Conference, with a slim chance of even going top if other results also go their way.
Dallas will make the relatively short trip hoping to break a tough run of their own after impressing with their start to the campaign.
With six wins, 22 points and just one defeat from their opening 11 outings, the Burn looked a force to be reckoned with in the playoff fight, albeit still at an early stage.
That impressive streak was eventually put to an end by consecutive 2-1 defeats at the hands of Vancouver Whitecaps and Minnesota United, before they temporarily bounced back with a 3-1 beating of Orlando City thanks to a Paul Arriola brace and a Franco Jara goal.
Dallas' celebrations were short-lived, though, as they again fell short in a contest against Vancouver Whitecaps last time out, with Lucas Cavallini and Deiber Caicedo netting the decisive goals in the first half.
Having now dropped away from the top two and below Sunday's opponents, Nico Estevez's side will aim to return to winning ways in what is lining up to be a crucial encounter in the fight for higher playoff spots.
