Dallas Cowboys head coach Jason Garrett may have some explaining to do Saturday morning. 

Garrett, an avid basketball fan, attended the Dallas Mavericks-Houston Rockets playoff game Friday evening. 

With the Rockets sporting a three-point lead with just under 13 seconds remaining, a grinning Garrett was spotted next to Houston's superstar guard James Harden. 

The American Airlines Center crowd apparently didn't take notice, or granted Garrett some good will after leading the Cowboys to the playoffs. 

In any event, it's not a good look and it could exacerbate frustration in Dallas after the Rockets prevailed with a 130-128 victory, sending the hometown Mavericks to the brink of elimination, holding a 3-0 series lead.
