Northampton have signed Crystal Palace midfielder Hiram Boateng and Millwall winger Gregg Wylde on loan for the rest of the season.
Boateng, 20, made his Premier League debut for Palace as a substitute in a 1-1 draw with Swansea in February.
Ex-Rangers player Wylde, 25, joined Millwall in the summer but has only made five appearances in League One.
Meanwhile, Northampton have terminated the contract of 30-year-old midfielder Joel Byrom.
"He (Boateng) is a player we have tracked for a while and we tried to bring him in last summer. He has impressed at both Plymouth and Bristol Rovers and we have done well to get him," said Cobblers boss Rob Page.
