Jets practice report: Injury and mistakes

CORTLAND, N.Y. -- Takeaways from Sunday at New York Jets training camp:

Tight end down: This wasn't a particularly sharp practice, and it took a bad turn in a 7-on-7 drill when promising tight end Jace Amaro hurt his right knee and sat out for the remainder of the practice with a big ice wrap on his knee. The Jets have big plans for their second-round pick, and losing him for any length of time would be a blow.

Good news/bad news: Despite tweeting late Saturday night that he's "fine," rookie safety Calvin Pryor sat out, one day after suffering a head injury. In fact, Pryor didn't even make it out to the practice field. The Jets have yet to reveal whether their first-round pick has suffered a concussion or not. Monday is a mandatory day off for the team, so Pryor will have at least two days of rest.

Guard Willie Colon (knee) was activated from the physically unable to perform list and participated in practice on a limited basis. He took part in positional drills but stayed out of team drills. Brian Winters worked at right guard, with Oday Aboushi at left guard. It'll be interesting to see how they rotate them once Colon is back to 100 percent.

QB update: Neither Geno Smith nor Michael Vick was that sharp. There were some pass-protection issues, so Smith and Vick did more scrambling than usual. As expected, Smith received the vast majority of the first-team reps, 15 to Vick's four. Smith was only 4-for-10, Vick was 4-for-7. There were some bright spots in a red-zone drill, as Smith tossed two short touchdowns, one to Amaro and the other to Chris Johnson. Vick had a scoring throw to Zach Sudfeld. Neither quarterback had a turnover. That's called a silver lining, folks.

Drops and penalties: Offensive coordinator Marty Mornhinweg couldn't have been thrilled with this practice. Stephen Hill, Shaq Evans and Jeremy Kerley dropped passes, and there were several penalties. The players did more push-ups than a platoon of Marines. At one point, Rex Ryan gathered the team for a brief meeting in the middle of the field. After that, they ran a few more plays.

CJ's back: After sitting out Saturday's contact drills, Johnson practiced fully, as expected. That's the plan: Every third day will be an off/limited day. The Jets are taking it easy with Johnson, seven months removed from knee surgery.

Medical report: Wide receiver Quincy Enunwa (hip), a sixth-round pick, remained on the sideline. ... Linebacker Tim Fugger (ankle) and rookie defensive end Zach Thompson (shoulder) sat out again.

Odds and ends: Safety Josh Bush made an interception in a 7-on-7 drill but dropped one in team drills. ... Seventh-round linebacker Trevor Reilly pancaked tight end Colin Anderson in a blitz pick-up drill. ... Wide receiver David Nelson and Dimitri Patterson exchanged heated words after a play. ... Another rough practice for rookie quarterback Tajh Boyd. ... The Jets have a mandatory day off Monday. They need it.
