A crew was busy Tuesday painting yard lines and logos on the grass with the New England Patriots blue in the north end zone and the Seattle Seahawks blue at the other end.
The NFL will roll the field into University of Phoenix Stadium at 11 a.m. Wednesdayon a movable barge with 500 steel wheels that will take close to an hour, said Ed Mangan, NFL field director.
"This turf system is great," he said. "It works very well being able to move the field in and out. It's part of the juggling match to where we have to manage time outside with time inside."
University of Phoenix Stadium, with its retractable roof, is the NFL's only stadium with a roll-away field that moves in and out on one massive turf tray. The tray weighs about 19 million pounds. That allows the grass to grow outside in the sunshine and then be moved indoors for game day.

This turf technology combines a soil and sand base with synthetic fibers that help the grass roots bind together. Water is applied under the sod so the roots grow deeper into the sand.
The Super Bowl will be the second game for this field, which was used for the Pro Bowl last Sunday. It was moved indoors on Jan. 23 and then back outside on Monday.
As much as it can, the NFL tries to limit foot traffic on the field for entertainment rehearsals.
"Too much traffic and it will kill it before the game," said Mangan, who also prepared the field for the 2008 Super Bowl.
The NFL grew the Tifway 419 hybrid turf at a sod farm in Alabama over the past two years. The sod was rolled up and shipped on Jan. 6 in 33 refrigerated tractor trailers. The trip to Arizona took 2 1/2 days.
The turf has some give to it to prevent player injuries, but it is soft and provides good footing and traction, Mangan said.
After the Super Bowl, Evergreen Turf will roll up the sod and donate it to a local high school.
