Ireland's scoreless draw against Russia was a tough match for Richard Dunne. He put in a fine performance -- even coming up with a goal-line clearance -- but a touchline collision left him with a gash on his face and blood on his shirt. And since Ireland apparently didn't bring him a spare, Dunne had to put on a blank shirt and have his No. 5 drawn on by hand before he could continue.
Here's video of the collision that caused the problem...
After the match, Dunne required four metal staples to close up the wound on his cheek that opened when his head bounced off the artificial pitch/running track.
