Jay O'Shea and Kerrea Gilbert were among the trialists to feature during MK Dons' friendly victory over St Neots Town.
Irish attacker O'Shea is available on a free transfer after leaving Birmingham City, and he has previously had loan spells at Middlesbrough, Stevenage and Port Vale.
He scored in the 4-1 success over St Neots and the match also saw former Arsenal youngster Gilbert feature for Karl Robinson's side.
Ex-Wolves defender John Dunleavy and goalkeeper Ian McLoughlin were involved as well, and Robinson was pleased with the trialists' contribution.
"We have had a number of trialists in and they all did really well," Robinson told the club's official website.
"We're running a small squad this year and in these games we need bodies to come in and help us out, and we are helping them out by getting them fit and letting other clubs look at them.
"We are looking at players all the time, we've got a few players that we're chasing at the moment. I'm looking for players who really make an impact."
