Shipp, a second-year running back out of Massachusetts, didn't have any carries last week against the Chargers, and has 8 attempts for 39 yards for the season.
Also as a result of Jones' bad ankle, Cardinals FB Joel Makovicka has been getting in practice at running back in case Shipp gets injured. Makovicka, a blocking back, only had one carry last year and has yet to touch the ball this season.
The swelling in Jones' ankle was down on Thursday and he practiced lightly on Friday. Jones is expected to play on Sunday against the Giants, but going against the Giants' 4th ranked defense in the NFL will not be an easy task even if his ankle was 100%. The Giants are ranked 7th in the NFL in defensive rushing by only allowing 81.7 yards per game.
NOTE: Cardinals WR David Boston also sat out practice until Friday with a sprained ankle which he received in last week's games against San Diego. Both Boston and Jones are listed as probable on this week's injury report.
