ALLEN PARK — Detroit Lions quarterback Matthew Stafford threw his first interception during training camp late in Monday’s practice. His pass was a little high, bounced off the hands of Brandon Pettigrew and into the hands of cornerback Bill Bentley. When Stafford was told on Friday that offensive coordinator Joe Lombardi had mentioned his interception-free camp, Stafford’s initial reaction was that he had been jinxed.

— Calvin Johnson practiced on Monday after he sat out Saturday night’s Lions’ preseason opener. Also returning to practice were Theo Riddick who suffered an abdominal injury in the game and Tahir Whitehead who left the game and appeared to be having a concussion test on the sideline.

Missing from Monday’s practice was right guard Larry Warford, safety Don Carey, along with Ziggy Ansah and TJ Jones who are on the physically unable to perform list.

— Music was played for a portion of practice to force more concentration. The playlist included “Higher Ground” by TNGHT and “Planet Rock” by Afrika Bambaataa and the Soulsonic Force. Caldwell pointed out he did not make the music selection, he lets the players have a hand in it.

— Defensive tackle Nick Fairley lined up with the twos (the second string) today but Caldwell said not to read too much into it. That is was a matter of reps. "It doesn't necessarily mean that they're ones or twos or threes,'' Caldwell said.

— Practice was moved indoors due to the rain. Since it was moved, it was closed to the public. The final practice set to be open to fans is at 2 p.m. on Wednesday.
