Dallas got a second half goal from Kenny Cooper, his first since the middle of May. Salt Lake had to adjust early on as they were a man down after a red card to Kenny Mansally in the 17th minute.
Jackson nearly put Dallas on the board early in the 10th minute. RSL keeper Nick Rimando made a couple key saves early on for the home side including one on Blas Perez.
RSL went down a man in the 17th, when Mansally was shown a straight red card for a tackle on Jackson. Referee Hilario Grajeda sent Mansally off after the Gambian international clattered into Jackson on the left side in the Dallas half.
Jackson was a problem for Salt Lake in the first half. In the 34th minute, Jackson took a great pass from Fabian Castillo in space in front of goal but once again Rimando would be up to the challenge.
Despite the man-advantage, it was Real Salt Lake that finally broke the deadlock on a counterattack in the 60th minute. Alvaro Saborio muscled his way past three Dallas defenders to get a foot on the end of a long, bouncing ball headed into the Dallas attacking third off Rimando's goal kick.
Dallas would make their break through in the second half though when Cooper would tie it up in the 72nd minute. Second-half sub Je-Vaughn Watson raced past Tony Beltran on the left wing and hammered a ball across the middle. Rimando got a glove on it, but the rebound fell to Cooper and the veteran forward wasted no time sending it into the back of the net.
The draw keeps Dallas below the red line once again in the playoff hunt but it does keep Salt Lake from clinching a playoff berth.
