Oh come on, there wasn't even a pool of blood on the ice. Like a good Canadian boy he skated off the ice and will be back in no time. Serious yes, but far less so than some previous ugly incidents...like Clint Malarchuk in 1989. I won't post the Youtube clip in all its gruesome, blood-spurting goodness (he also lived thanks to quick thinking).
Any fan of Hockey knows, especially come playoff time, that players are routinely stitched up so fast they may not miss a shift.
Now, if a baseball player gets a hangnail he's on the DL!!!
Or god forbid a soccer player pulls a hammy during an Olympic class dive.
The only sport that comes close to hockey for toughness are those looney Aussies and their Aussie Rules Football....which is quite fun to watch.
