The Jets have announced their practice squad for the start of the season:

RB Jehuu Caulcrick, (6-0/250/Michigan State/Findley Lake, NY)
DB Emanuel Cook, (5-10/185/South Carolina/West Palm Beach, FL)
ILB Kenwin Cummings, (6-3/250/Wingate/Maxton, NC)
S Keith Fitzhugh, (5-11/205/Mississippi State/Jacksonville, FL)
WR Marcus Henry, (6-4/212/Kansas/Lawton, OK)
DT Matt Kroul, (6-3/280/Iowa/Mount Vernon, IA)
OT Ryan McKee, (6-6/291/Southern Mississippi/Daphne, AL)
TE Jack Simmons, (6-4/246/Minnesota/Mundelein, IL)

I'm sure some of these names sound familiar. These are mainly Jets preseason players who didn't make the final roster. The team gets to try and develop the youngsters with potential like Caulcrick, Cummings, and Henry.
