Romo was hurt in the third quarter of the Cowboys' 20-17 overtime loss to the Washington Redskins when he took a knee to the back from Redskins linebacker Keenan Robinson.
He returned to the game for the final two minutes of regulation and the team's lone possession in overtime. Romo finished with 209 yards passing and one touchdown.
The injury prompted Jones to visit the sidelines during the game and deliver the news to Garrett himself that Romo was able to return to the game.
"I think the ideal situation is to get it communicated as quickly as possible and he felt like he could do it," Garrett said, according to ESPN.com. "It wasn't a big deal to me at all."
Romo was diagnosed with a back bruise after X-rays came back negative. He's expected to play in Sunday's game against the Arizona Cardinals. Garrett said he doesn't care how it looks that Jones, who has long been known to visit the sidelines during games, came down to the sidelines after being concerned about his franchise quarterback.
"Don't worry about [how] things are being portrayed," Garrett said.
