Barnet have signed Nottingham Forest midfielder Mark Byrne on loan until the end of the season, while Crystal Palace defender Matty Parsons has signed for one-month.
The League Two side are battling against relegation and manager Paul Fairclough has decided to add to his squad in the loan window.
Byrne scored four goals in 15 league starts for the Underhill side in a loan earlier in the season, but that was cut short by injury.
However, after a lengthy rehabilitation programme, the 22-year-old has been back in training with Forest and has returned to Barnet in search of first-team football.
Palace left-back Parsons has also been signed by Fairclough and will be at Underhill for one month.
