So Shane Carwin tweeted about a knee injury that’s keeping him from making the trip to the UK for this weekend’s event. No biggie, though. Tis but a scratch, according to his management:

Carwin first reported the knee injury on his Twitter account saying, “ATTN UK Fans: I hurt my knee training and I will not be able to make the signing with the amazing people @FearlessUK.”

Carwin’s manager Jason Genet of Ingrained Media told that he injured the knee while in wrestling practice, but he suffered no major tears or damage to the knee.

The injury was enough for Carwin to cancel a trip to England this week for a signing, but with time to rehab and recover the former heavyweight champion should be ready in time for his Dec. 15 showdown with Roy Nelson.

Should isn’t the most reassuring word in this scenario. Should has become the new precursor to the gypsy lady’s latest kick to our collective balls. Dan Henderson hurts his knee but should still be able to fight Jon Jones. Jose Aldo scraped up his foot in a motorcycle accident but should still be able to fight Frankie Edgar. And yet here we are with no Henderson vs Jones and no Aldo vs Edgar. So telling me Carwin hurt his knee but should be able to fight Nelson?
