DALLAS (AP) — Radek Faksa made a promise to his 2 1/2-year-old son when they were playing together before the Dallas Stars took the ice for Game 7.

Faksa did indeed score in his return to the lineup after missing four games because of an undisclosed injury. His go-ahead goal came on a backhander 44 seconds into the third period, after his son had been taken home, and Dallas beat the defending Stanley Cup champion Vegas Golden Knights 2-1 on Sunday night to wrap up the first-round series.

“I’m happy I did,” Faksa said. “And so I can show him the video in the morning, and we can watch it together.”

Only captain Jamie Benn and Tyler Seguin have played longer for the Stars than Faksa, a fourth-liner in his ninth season who got his goal from the circle to the left of goalie Adin Hill. Dallas also got another Game 7 goal from 20-year-old Wyatt Johnston.
