Still, his appearance is an indication he could be closer to returning.
Romo broke his left collarbone on Oct. 25. He is expected to miss at least two more games to let the injury heal.
Garrett adds that a decision on if or when he returns "will be based on the medical evidence that we have."
Romo has lobbed balls on the field before each of the last two games, but this was the first time he was seen throwing to teammates during the portion of practice open to media.
