Cribbs sat out last week's voluntary minicamp, but had a face-to-face discussion with new coach Eric Mangini last Thursday.
"He's absolutely making a good faith effort to show how important football is to him and his teammates are to him," said Cribbs' agent, J.R. Rickert. "Obviously his contract is important to him as well."
Rickert did not negotiate Cribbs' current six-year, $6.7 million deal. The former Pro Bowler is scheduled to make $620,000, $635,000, $650,000 and $790,000 over the next four years.
While previous reports indicated Cribbs would demand a trade if a new deal isn't reached, Rickert denied ever saying that. He refused to confirm or deny that would be the next step.
"Josh and I have had confidential discussions about what steps we should and shouldn't take," Rickert said. "He's optimistic that this can work out for everybody, and that's the approach we'll take going forward."
