Preston boss Phil Brown remains keen to bring goalkeeper Iain Turner to Deepdale but is also looking at David Lucas.
Turner, who spent three months on loan with North End last season, is currently a free agent having left Everton and is training with League Two side Bradford as he looks for a new club.
Brown's hands remain tied as he waits for current number one Andy Lonergan, who was unable to agree personal terms with Leeds earlier this summer, to decide his future.
In order to keep his bases covered, Brown has taken the opportunity to have a look at Lucas in Saturday's pre-season draw at Falkirk - himself a free agent after being released by Swindon - almost eight years since he last played for the club.
Brown told the Lancashire Evening Post: "For sure, Iain Turner is still in my plans - I would like to push the button on that one as soon as I can. Iain is training with Bradford to keep his fitness levels up. For me, bringing Iain here is a no-brainer. He's a free transfer and fingers crossed, affordable with regards to a contract.
"Two or three years down the line, I think the club can make money on him, so for me he's an asset we need to be seriously considering. I know we are doing that, but I have to cover myself just in case it doesn't happen. My job is to make sure I have someone between the sticks come August 6."
