Wrexham will not be signing former Swansea City, Ipswich Town and Wigan Athletic striker Jason Scotland.
The 36-year-old former Trinidad & Tobago international is a free agent and had been training with the Dragons.
He played 45 minutes as Wrexham reserves suffered a 5-0 defeat against Stoke City on Tuesday.
"I am not going to be taking it any further," Wrexham manager Gary Mills told the Evening Leader.
"You get someone in to take a look at them and it is just not quite right for what I am looking for.
"I need someone to come in and hit the ground running and Jason is not at that stage."
Scotland was released by Hamilton Academical at the end of the 2014-15 season.
He scored 53 goals in his two seasons at Swansea and was a member of his country's 2006 World Cup squad.
Wrexham are short of striking options with top-scorer James Gray ruled out with injury.
Gray, 23, has undergone surgery on a broken hand he suffered during his side's 0-0 draw against Grimsby Town in the National League.
