The frigid conditions were not enough to deter 72,713 from taking in this game, which advances to the fourth quarter with Denver in field-position purgatory back at its 1-yard-line. The temperature has risen to 21 degrees tonight, with the wind chill now at 11.

8:38 P.M. MST: Bryce Fisher gets to Jay Cutler on third down … but Cutler holds on to the football, and managed to step one yard out of the end zone, avoiding a safety — but forcing Paul Ernster to punt from deep in his end zone. Ernster kicks a 40-yard punt that Nate Burleson returns six yards to the Denver 36.

8:42 P.M. MST: Huge third-and-4 … and Elvis Dumervil collapses the pocket along with Gerard Warren. Dumervil gets credit for the sack, setting up a 52-yard Josh Brown field-goal attempt … or perhaps no, as Brown pooches the punt, which Darrent Williams comes forward to field, which he proceeds to muff … and then recover on his own.

8:43 P.M. MST: Denver didn’t lose the ball, but might have lost something far more valuabke, as Al Wilson has yet to rise after the play.

8:47 P.M. MST: Wilson is still on the grass. He momentarily sat up, but is laying down on the cold grass at around the Denver 20-yard-line once again. A chant of “Wil-son, Wil-son, Wil-son,” rises from the frigid fans as virtually the entire Broncos team encircles the All-Pro linebacker.

8:52 P.M. MST: An immobilized Wilson leaves the field. Meanwhile, Tatum Bell is injured one play later and is helped by the team’s training staff to the sidelines.

8:55 P.M. MST: It appears that Wilson’s injury has — quite understandably — dripped the liveliness from this crowd, and perhaps the Broncos. Denver goes three-and-out and punts; Seattle takes over at its 39-yard-line with 9:42 left.

8:59 P.M. MST: Three plays later, Seattle is in the end zone.

9:02 P.M. MST: Turnover No. 4 comes when Brian Clark fumbles the football on the ensuing return. Seattle’s Joe Tafoya recovers the fumble at the Denver 40.

9:12 P.M. MST: Since Wilson left the game, nothing has gone right for the Broncos; the team yields a field goal, and then a Jay Cutler pass is tipped and intercepted.

9:13 P.M. MST: NBC’s Andrea Kremer reported that Wilson was moving his extremities and was taken to a local hospital for “precautionary measures.”

9:16 P.M. MST: The Wilson-less defense gamely holds Seattle to a field goal, and gives Cutler one more opportunity.

10:46 P.M. MST: Back in the press box after a crushing defeat for the Broncos. It gives them their third straight home defeat — the longest skid in Denver since 2002 — and places them in a tie for the last wild-card slot with Cincinnati, Kansas City, Jacksonville and the New York Jets. All trail their respective divisional leaders by at least two games with four to play.
