Dion-Curtis Henry has been invited on a two-week trial at Crystal Palace.
The 19-year-old is currently third-choice keeper at Peterborough United, behind on-loan Spurs player Luke McGee and veteran Mark Tyler.
Henry graduated from the Posh Academy, but has made just one substitute appearance for the first team, in a 5-3 win over Millwall in October 2015.
However, he did make 12 appearances on loan with Boston United this season in the National League North.
The teenager has previously also spent time on trial at Leicester City.
Henry is out of contract at the ABAX Stadium at the end of this season and no new deal has yet been offered, even though there is no chance of McGee returning to the club next season.
