I'm waking up, I feel it in my bones ("Challenge")

Enrico tried to brace himself against the challenger's charge, but the male shifted just enough to slam into Enrico's injured shoulder and Enrico staggered with an unbidden gasp of pain as the leg folded. His gaze went white with pain for a moment, and a sudden weight staggered him further, throwing him chest-first against the ground with Chaos' forelimbs wrapped around his neck. His head was pressed down against the ground, and however he struggled he couldn't get his legs beneath him to squirm out of the larger wolf's hold. His vision was fuzzing, breath coming in faint pants through the increasing pressure of Chaos' hold. "Nnn..." he tried to snarl. He couldn't give up. He had to fight. His paws scrabbled at the ground, the movements getting weaker and weaker as black crowded in around him. No. No, he was done. He could do no more. "I yield," he finally gasped out. Chaos immediately released him, leaving him gasping and coughing on the ground. Flecks of blood stained the ground before him as he coughed, and it was all he could do to gulp in the fresh cold air.
