Barnsley eye two more trialists
Marvin Robinson and Craig Ireland are both set to train with The Tykes' first-team on Wednesday and feature in the weekend game against Bradford City.
The 23-year-old striker Robinson was released by debt-ridden Derby County at the end of last summer and had a loan spell at Stoke City during Thordarson's time at the club, as well as spells with Exeter City and Tranmere Rovers.
Ireland spent the last two-and-a-half years at Notts County where he appeared in over 80 games for The Magpies.
Thordarson told the club's official website: "We have had Marvin and Craig with us today and we will look more closely at them.
"I am to involve all the trialists at some stage against Bradford this weekend."
