I'm not sure which incident you're talking about, Michael, but I didn't see any penalties.� Closest was the controversial free kick decision (not awarded) when Owen was brought down just outside the box.� Only saw one replay and in poor quality, so couldn't tell if it was a foul or no, but there's no way it could be given as a penalty.
Also, Leeds aren't really "a League 1 side".� They're Championship material, and no doubt viewed the fixture as their biggest game of the season.
On the about four minutes into the second half I believe. Leeds defender had his leg at (i think) Gibson's waist hit and took him out. The commentators later agreed it should've been a penalty.
But not an excuse for losing to a League 1 team.
