With Kevin Kolb and Michael Vick off, rookie fourth-round pick Mike Kafka got all the snaps at quarterback Thursday morning. It was the last practice before veterans joined camp, and it ended early.

Eagles veterans are required to report for a 7 p.m. meeting Thursday night. Wide receiver DeSean Jackson ran laps around the practice field before the morning practice. There was speculation he opted out of the last week of OTA’s to express unhappiness with his contract.

Still missing from action is unsigned rookie first-round draft pick Brandon Graham. Barring a minor negotiating miracle, he will miss the start of contact Saturday. Graham begins falling behind when he misses next week. He also could be flirting with injury, as late signees tend to lose their conditioning.

Just when it seemed the Eagles were fine at wide receiver they worked out Jared Perry (6-1, 180), a rookie who teamed with Jeremy Maclin at Missouri, and Kelley Washington (6-3, 218).

Perry caught 46 passes for 696 yards and 6 TD’s last year, after reconstructive surgery in his right shoulder.

Washington, 30, played for the Bengals (2003-06, the Patriots (2007-08) and the Ravens (2009). He caught 34 passes for 431 yards (12.7 average) and two TD’s in the 2009 regular season and an 11-yard pass in the playoffs against the Colts.

Mornhinweg was incredulous when a reporter said the Eagles’ system would make Kevin Kolb more prone to interceptions. So was I.

After an “Are you serious look?” look, Mornhinweg’s response was, “It’s just common sense. You want him to throw touchdowns, not interceptions.”

The Eagles’ 3:30 p.m. practice Friday is closed to the public. The first full-squad practices are Saturday at 8:15 a.m. and 2:45 p.m. Camp hotline: 215-320-5160
