Erin Henderson came to work Monday and told Vikings linebackers coach Fred Pagac he'd had some bad dreams.
Henderson was burned by Andrew Luck's 30-yard touchdown pass to Reggie Wayne in the final seconds of the first half in the Vikings' 23-20 loss to the Colts on Sunday.
Wayne bumped by cornerback Antoine Winfield and headed up the middle, outrunning Henderson before catching the pass in the end zone before Vikings safeties could converge.
"I told [Pagac] that I had nightmares about that play," Henderson said. "He told me, 'Good, you should.' "
The outside linebacker said he was in decent position, but made a bad play on the ball.
"I just tried to make a play on the ball too soon," he said. "When I turned around to look at it, I misjudged it completely."
Henderson said he was capable of winning the matchup with a wide receiver.
"I had some time last year playing the same position," he said. "And doing the same things. And I didn't give up anything across the middle. So, it's one of those things. I was trying to take the next step and get my head back there and I got nosy and he kept running. It is what it is."
