Cheltenham have extended Shaun Jeffers' loan spell from Coventry until January 1.
The teenager, who made his England Under-19 debut last week, has scored two goals in six appearances for the League Two club during his initial month-long stay at Whaddon Road.
"It is a big boost for the club because he has done ever so well," said Town manager Mark Yates.
"He is getting stronger everyday and it won't be long before he will be starting games. I am delighted to secure his services and I have to thank Coventry and Aidy Boothroyd. They know we are looking after him and he is doing very well here.
"We are delighted we have been able to keep him a bit longer."
