"I'm not sure. It doesn't look like it as of now," Cason said by phone. "I don't know."
"I mean, we're we were making progress, of course," said Cason, a cornerback from Arizona who went to the Chargers with the 27th overall pick. "I've kind of just heard little details of it from my agent. I just control what I can control, my play on the field."
Cason is the Chargers' only draft pick who hasn't agreed to a deal. Rookies and selected veterans reported Sunday night and were scheduled to hold their first practice at 10:30 a.m. Monday.
Agent Ron Slavin said in an e-mail there was "no news to report."
General manager A.J. Smith didn't immediately return phone calls, and team negotiator Ed McGuire didn't return an e-mail seeking comment.
Cason, who played at Arizona, was at his apartment in San Diego and would be able to get to camp quickly once a deal is reached.
"That's the most difficult thing to get through, of course, is the business side of it," Cason said. "You never know what can happen. It's a big difference in that way, not being able to show up the first day because of the business side.
"I've been keeping calm, keeping my cool. Really, I'm just trying to keep working out, not letting it affect me."
