Grosicki’s Poland were held to a 0-0 draw in a top-of-the-table clash with Austria, which saw their lead at the top of Group G cut to two points after Slovenia’s win over Israel.
The Tigers’ winger was on the pitch for 70 minutes – creating the Poles’ best chance for Robert Lewandowski – before being substituted in the clash at the National Stadium in Warsaw.
Magennis, meanwhile, was introduced into the action for the final 20 minutes of Northern Ireland’s 2-0 defeat at the hands of Germany at Windsor Park despite a spirited display.
Marcel Halstenberg’s stunning half-volley early in the second half and a stoppage-time goal by Serge Gnabry gave Joachim Low’s men victory.
The defeat – which saw Michael O’Neill’s side fail to score at home for the first time in their last eight international matches – resulted in Northern Ireland dropping to second in Group C, with the Germans moving above them on goal difference.
