Former Sheffield United winger Keith Gillespie has joined Leeds on trial.
The 33-year-old has been training with the squad and played in a friendly against Rochdale earlier this week.
Ex-Celtic defender Mo Camara, 33, who was also on trial at Elland Road, has signed for St Mirren until the end of the season.
"I played with Keith at Blackburn and when you get the chance to look at players like that you do it," manager Simon Grayson told the club website.
Grayson added: "Keith has left Sheffield United and trained with us for the last week."
Gillespie, who has won 81 caps for Northern Ireland, began his career with Manchester United before joining Newcastle in 1995. After short stays at Wigan and Leicester, the 33-year-old moved to Sheffield United, winning promotion to the Premier League with the Blades.
He spent a month on loan at Championship side Charlton at the end of 2008.
He was subsequently released from his contract at Bramall Lane and is now a free agent.
"It's promising that a Northern Ireland international wants to try and play for the club," said Grayson.
