Video: Ouch! Darran O'Sullivan runs into a fence during Kerry training last week at full tilt
Questions were asked on Sunday when Darran O'Sullivan arrived to the All-Ireland with a bandage on his nose but this video more than explains it.
The flying forward has been dogged niggling injuries all season but it doesn't help when you plough into the perimeter fence at Fitzgerald Stadium at full tilt.
He tweeted: "Testing the hamstrings last week, forgot to check the brakes!" and posted this video in intagram. It looks very painful.
The Kerry 'B' side appear to have been wearing the Donegal colours during the session.
