Leeds have taken Keith Gillespie and Mo Camara on trial.
Former Sheffield United winger Gillespie, 33, and defender Camara - who was released by Derby earlier this month - both played in a behind-closed-doors game with Rochdale this week.
Camara, also 33, spent time playing under United manager Simon Grayson at Blackpool earlier this season.
Grayson is keen to see what the duo can do and told the club`s official website: "Keith has left Sheffield United and trained with us for the last week and it`s the same situation with Mo.
"I worked with Mo earlier this season and he is a good, experienced left-back. I played with Keith at Blackburn and when you get the chance to look at players like that, you do it.
"It`s promising a Northern Ireland international wants to try and play for the club and Mo has played at the highest level as well so it`s good to have players like that wanting to play for us - whether they do or not, we will wait and see."
