The Summerville, S.C., product dropped one pass. Then he dropped another in a drill where he ran short routes and turned to try and catch a ball already in the air.
Teammate Israel Troupe patted Green on the head after he caught the next ball.
Later, Green showed why he was among the top receiver recruits in the nation when he jumped and reached across his body to catch a pass thrown behind him.
"It was fun," said Green, who is wearing No. 8. "Coaches getting on you. You think you know everything then the coaches get on you. It was ... fun to learn some new things and get everything down."
Georgia will have 25 more practices before it opens the season Aug. 30 against Georgia Southern, but Green could be limited today. The 6-foot-4, 202-pounder sat out the end of practice because he said he re-aggravated a groin injury.
"I thought he was a little nervous today and had a little nervous energy," offensive coordinator Mike Bobo said. "You could tell he's smooth and he's got strong hands. It's early. First day. A little bit of freshman nerve, I think."

Each session lasted less than two hours.
