Faksa made it 1-1 at 2:48 when he tipped Esa Lindell's high shot off the ice and over Howard's left shoulder.
Spezza gave Dallas a 2-1 lead at 8:55, tipping a John Klingberg shot with the Stars on a 5-on-3 power play. It was Spezza's first goal since Dec. 9 against the Vegas Golden Knights (14 games).
"It was huge for [Spezza] to get that one," said Klingberg, who extended his point streak to seven games (two goals, 10 assists). "He's been struggling a bit, so I was really happy to see him come back into the line and score a couple like that."
Athanasiou made it 2-2 at 11:43 of the second, taking a long pass from Bertuzzi and scoring on a breakaway.
