He threw the ball pretty accurately from the pocket.
The Vikings played their first game without Cook, who was lost for the season with a torn ACL suffered October 1 against Detroit.
Despite the tricks, the Bears were done in by their own self-inflicted wounds. But it was fun, too: a fake-punt touchdown pass from Pat O'Donnell (first National Football League throw) to Benny Cunningham (first Bears touchdown); that tipped-ball touchdown to Miller, a play Trubisky extended with his legs; and a Jordan Howard-to-Miller-to-Trubisky two-point razzle dazzler.
The Raiders (2-3), meanwhile, lost their third straight game and look lost without quarterback Derek Carr, who is still out with a broken bone in his back - replacement EJ Manuel completed 13 of 26 passes for 159 yards and one touchdown.
However, Jeff Rodgers saw something to exploit.
Kai Forbath, who joined the Vikings last November, had never played at Soldier Field, but he understood from teammates the struggles that Minnesota has encountered on the southwest shore of Lake Michigan. His first touchdown pass was a bit lucky, but it still counts.
The Bears lined up to punt on a fourth down at the Minnesota 38 on the next possession.
Bears rookie quarterback Mitchell Trubisky gets set to unload on Monday night against the Vikings.
"You can tell he definitely has some skill and he is going to be a player", Smith said. The punter did his job.
"Great throw", Cunningham said. A pass to the end zone was tipped by Vikings safety Andrew Sendejo and landed in the hands of Miller.
Signed to a three-year, $15 million deal, Latavius Murray finds himself thrust into the lead-back role after seeing Cook exit following his non-contact injury.
The basic reaction among Bears fans: Throw something at the TV, cuss at the guy in the next seat and say, "Here we go again". I knew somebody was going to score.
"It was a great play call", O'Donnell added. "Throughout the week we talked, missed it a couple times".
Keenum rejuvenated the Vikings' offense. But it got the Bears back in the game after they fell behind by eight points in the third quarter.
This year's Chicago Bears would not be what most would consider a team with a revolutionary offense. That's when the second example of trickery took place.
With rookie quarterback Mitch Trubisky at the helm, the Bears needed more fakery to put up points. Trubisky will make mistakes like throwing late picks to Pro Bowl safeties, sure. He's still learning now though, and that play cost the Bears a winnable game to a division rival.
We'll take that over Mike Glennon.
"You know, he was just ready to go", said receiver Stefon Diggs. "It's a kid's game that we're playing, so why not have fun and do the things that make you happy?" Trubisky, however, was picked off by Harrison Smith on the very next play while trying to connect with tight end Zach Miller. The radical plays kept the team close, but it wasn't quite enough to earn the team a win.
