Jim McAlister made his debut for Dundee after becoming manager Barry Smith's third signing in the days leading up to the club's top-flight return.
The 26-year-old winger, released by Hamilton, was snapped up shortly before the 0-0 draw with Kilmarnock.
Dundee had already signed released Bradford City forward Mark Stewart and Davide Grassi after the defender's exit from Brussels.
McAlister had spent two seasons with Accies, latterly in Division One.
The Rothesay-born winger had started his career with Morton and famously, following a friendly against Unirea Urziceni, was approached by the Romanian champions' coach, Dan Petrescu.
However, he rejected the opportunity of moving to Unirea and subsequently had a trial with English Championship outfit Watford.
McAlister was released by First Division outfit Morton in summer 2010 and joined Hamilton in the Scottish Premier League.
Now, after a season back in Division One and following a trial with Carlisle United, he has joined Dundee back in the top flight.
Dundee had suggested that they needed six additions to their squad after being handed a late entry in the SPL to replace financially stricken Rangers.
