The Jets' ground game may be grounded before it takes off for Indianapolis.

Running back Chris Ivory (groin) was limited in practice Saturday and is listed as questionable for the prime-time showdown with the Andrew Luck and the Colts on Monday Night Football.

Veteran cornerback Antonio Cromartie (knee sprain) also was limited in practice and is questionable for the game.

The uncertainty surrounding Cromartie's status was expected, considering he had to be carted off the field last week during the Jets' 31-10 win over the Cleveland Browns. But it's unclear if Ivory's lingering groin issue will keep him out against the Colts. The bruising back -- who rushed for 91 yards and two touchdowns against the Browns -- has been limited in practice the past three days.

On Friday, however, Jets coach Todd Bowles said "yes" he expects Ivory to be fine for the game.

But if Ivory is unable to play, the Jets will rely on the dependable Bilal Powell and offseason pickup Zac Stacy, who was inactive last week.

Quarterback Geno Smith (jaw) and linebacker Lorenzo Mauldin (concussion) have been ruled out and cornerback Darrin Walls (hamstring) is doubtful. The good news is, rookie speedster Devin Smith (ribs) practiced fully this week and is probable to play.

The Colts, meanwhile, will be without their two top cornerbacks Gregory Toler (neck) and Darius Butler (hip). Receiver T.Y. Hilton (knee) and six-time Pro Bowl linebacker Robert Mathis (Achilles) are questionable.
