Shipp dislocates ankle during scrimmage
Shipp got caught underneath a pile during a routine running play and got his left leg wrenched in the artificial turf at Northern Arizona University's Skydome.
After several minutes on the turf, Shipp was loaded on a cart and led off the field.
The injury was not as bad as it initially appeared to be, said Cardinals coach Dennis Green.
"It did not break through the skin, which means it probably does not need an operation," Green said.
In the offseason, Green named Emmitt Smith the starter at running back.
But with the 35-year-old Smith's durability a question mark, Shipp was expected to see plenty of carries this season.
Shipp led the Cardinals with 830 yards rushing last year, including games of 165 and 141 yards.
"He took a bad spill and it don't look good right now," Smith said of Shipp. "But he's young and resilient and he's in great shape.
"I've been on football fields for a long time and I've seen some bad things happen, but not many to people I've been close to. The kid is a like a brother to me," added Smith. "Watching him go down is like watching a brother go down. It hurts."
With Shipp's injury, Damien Anderson now moves up on the depth.
The Cardinale offense won the scrimmage 20-11, scoring three touchdowns.
First-round draft pick Larry Fitzgerald did not make a catch.
"The offense did a pretty good job," Green said. "But we're not nearly as sharp as we want to be."
Arizona opens its preseason schedule on Aug. 14 at Minnesota.
