Denali National Park ranger Steve Griggs confirmed that a grizzly bear suffered a mild sprain when it mauled a hunter Wednesday, the 400-pound animal awkwardly twisting its paw while crushing the man's skull. 'Looks like he slipped on some flesh he was tearing off and just came down on it wrong,' said Griggs, adding that the bear also appeared to have strained its neck as it tossed the man's torso back and forth in its mouth. 'It's a slight sprain. Doesn't look broken. The paw is a little tender, but he'll be all right as long as he doesn't put too much weight on it, rests up, and keeps it under a cool stream to reduce swelling.' Griggs confirmed that the bear should have no problem catching salmon but may limp for a week or so.
