Chimdi Chekwa has dealt with so much in his first two NFL seasons that a matchup with wide receiver James Jones in practice seemed fairly easy in comparison for the Oakland cornerback.

At least that's how Chekwa made it look Thursday.

The former fourth-round draft pick dropped back into coverage, stopped, then made a quick break forward and got in front of Jones to knock away the pass thrown by quarterback Matt Schaub.

Not intercepting the ball left Chekwa shaking his head as he jogged back to the huddle.

"James does a great job of getting to the ball, regardless of where the ball's thrown," Chekwa said. "It's hard to pick off a ball that's going to James Jones but it should have been a pick."

Chekwa has made several similar plays during the first week of training camp since stepping in for injured projected starter D.J. Hayden.

Hayden, the 12th overall pick in 2013, is recovering from offseason surgery and likely to miss the first month of camp. He has spent his afternoons watching practice from the sidelines, another blow for a player Oakland was banking on to play a major role in the secondary.
