"I don't think I'm quite back to full speed yet, but I'm feeling pretty good," Robinson said Tuesday.
The 58-year-old coach was knocked unconscious and sustained a concussion after being run over by receiver Teddy Williams during a punt return drill July 30, the first day the Cowboys were in pads. Williams injured his hamstring in the collision.
"My energy's not quite back to where it needs to be," Robinson said. "If I start to jog back and forth, that feels strange. I'm walking everywhere I go right now, but hopefully that will come back soon."
Robinson has been back at practice for about a week and plans to be on the sideline Thursday night when the Cowboys play their preseason opener at home against Denver.
This is his first season with Dallas after coming from the Super Bowl champion Green Bay Packers. Robinson is also the assistant head coach for Jason Garrett.
Robinson, going into his 22nd season as an NFL coach with his sixth team, said he got "a ton of texts and calls" from people who heard about what happened.
"I've had a lot of great caring and thoughts and prayers and all that," he said. "All that is certainly tremendously appreciated."
Robinson previously coached for Atlanta, Indianapolis, New York Giants, New Orleans and Green Bay, and played five NFL seasons as a receiver (Giants, 1976-79; and San Francisco, 1980).
He said he had never been "knocked out cold" before though he is sure that wasn't his first concussion.
"I probably had one, or two, back 25-30 years ago," he said. "Like we've all said, the protocol on that has changed an awful lot. I'm certain that I had one, nothing like that one."
