NIKOLAI, Alaska (AP) -- Musher Ben Stamm has scratched from the Iditarod Trail Sled Dog Race.
He scratched this morning in Nikolai.
Race officials say the Argyle, Wisconsin, musher sustained a knee injury and made the decision to scratch based on the welfare of his team.
Of the original field of 82 mushers, he's the 15th to drop out of this year's race.
Still not much movement in today's field.
Six mushers are at the Iditarod checkpoint, the halfway point of 1100-mile race from Anchorage to Nome.
Lance Mackey arrived at 12:11 a.m., followed six minutes later by Paul Gebhart.
Two other mushers came after 6 a.m. -- Ed Iten and Mitch Seavey.
Both Tollef Monson and Cim Smyth arrived after 8 a.m.
So far, no one has left the checkpoint.
