Mansfield Town have signed midfielders Ricky Ravenhill and Junior Brown on contracts until the end of the season.
Ravenhill, 33, has not been a regular for Northampton Town this season and left the Cobblers on Tuesday.
Brown, 25, had been on loan from Oxford United since late November, and left the U's by mutual consent.
"Ricky will add a wealth of experience. He is someone who has achieved success in League Two previously," said Stags boss Adam Murray.
"[He] is a leader and organiser - specific qualities which I think we needed. Ricky will raise the standards."
Ravenhill began with Barnsley and has made a total of 488 appearances during his career, scoring 23 goals and gaining four promotions.
He also won the League Two title with Notts County in 2009-10.
