 Denver looked strong early and led the visiting 49ers 13–3 at halftime, but San Francisco used a stingy goal-line defense and a heavy dose of NFC rushing champ Frank Gore to take a lead late into the second half.Cornerback Darrent Williams (playing in what would tragically be his final game) also left the game in the second half due to a shoulder injury.With just 90 seconds left on the clock, rookie QB Jay Cutler tossed a nine-yard touchdown to tie the game at 23.
