CORTLAND (AP) -- Calvin Pryor will have to wait another week for his NFL debut.
The New York Jets' rookie safety, who just returned from a concussion, will not play in the team's preseason opener against the Indianapolis Colts on Thursday night.
"He missed a lot of work," Ryan said, adding that Pryor is physically ready to play. "We'll get him back and get him up to speed for the next one. We kind of waited this long. Let's just get him a fresh start, make sure everything is good. I think that'll be good for him."
The first-round pick suffered a head injury on July 26 during a special teams drill. Pryor returned to full contact Monday, and has participated in meetings the past several days.
"I don't want him to make a poor account for himself," Ryan said. "I would rather give him a full week of preparation and let him get ready."
The Jets' second preseason game is Aug. 16 at Cincinnati.
Wide receiver Shaq Evans, a fourth-round pick out of UCLA, has a "severe" and nagging shoulder injury that Ryan says "looks pretty bad," and has kept him very limited at camp. Ryan did not rule out putting Evans on injured reserve.
"I don't know, we'll see how that goes," Ryan said, "but it doesn't look good right now."
Wide receiver Jeremy Kerley missed practice with an illness, while running back Bilal Powell (hamstring) and cornerback Johnny Patrick (hamstring) were limited. Tackle Brent Qvale was out with a concussion.
Ryan says the team's starters will probably play into the second quarter against the Colts. Geno Smith will start at quarterback, but Michael Vick could get a few snaps with the starters after the first quarter.
NOTES: Ryan's son Seth, a wide receiver at Clemson, broke a collarbone during practice Monday. The Jets coach said the first text he got after the news was from former QB Mark Sanchez, now with Philadelphia. ... LB Jermaine Cunningham was placed on season-ending injured reserve with a torn Achilles tendon, suffered in the scrimmage last Saturday night. The Jets signed OT Bruce Campbell to take Cunningham's spot. Campbell was a fourth-round pick by Oakland in 2010, and he has also spent time with Carolina.
