Cheltenham boss Martin Allen has rewarded duo Elvis Hammond and Drissa Diallo with 18-month contracts.
Hammond joined The Robins in November on a short-term contract that was due to expire in January.
However, Allen has been impressed enough with the former Leicester man to retain his services until the summer of 2010.
Likewise, Diallo has joined the club permanently after the 35-year-old impressed while on loan from MK Dons.
"Elvis is getting sharper and with hard work and dedication on his part, he will get better and better," Allen said.
"I believe these are good deals for the club and another very positive move in the right direction."
