"Green Bay Packers cornerback Sam Shields probably avoided a butt-chewing for trying to bring an interception out from the end zone late in the third quarter.

But there are better ways to do it than suffering a concussion.

Shields may have to miss the Minnesota Vikings game next week because of his decision to return a ball he caught 7 yards deep in the end zone.

Shields had inside position on quarterback Sam Bradford's poorly thrown fade route to receiver Danario Alexander and reached up with two hands to snare it in the back corner of the end zone. He then took off running laterally across the end zone before eventually being tackled and struck hard.

NFL rules state that is not a safety because the pass was not a defensive play that pinned Shields in the end zone. The rules did not save him from getting clobbered, however."
