The Bears have signed former Cowboys running back Marion Barber to a two-year contract.

Bears running back Matt Forte wants a new contract, but he still reported to training camp on time. Forte reported to camp on Friday along with Chicago's other veterans, according to a source.

The Bears have traded tight end Greg Olsen to the Panthers in exchange for a third-round pick in the 2012 draft, according to a league source. Olsen then agreed to a four-year, $24 million extension with $10 million guaranteed, added a source. "I think it's bittersweet," Olsen said. "I've made it clear since the day I got here that I've really enjoyed my time here in Chicago. My plans all along, obviously, were to play my career here. ... The guys on the team have been awesome. And the fans obviously are second to none and this city really embraces their team. ... At the same time, I feel like for my career and going forward to go join a team that has so much promise and the guys they have in place already down there. And [offensive coordinator] Rob Chudzinski [is] a guy that I know from my college days. And what he's done with tight ends and how his offense focused around that position. So I feel like it's a great opportunity for me going forward and it's something I'm looking forward to."

Former Cowboys wide receiver Roy Williams wants to sign with the Bears, according to a source. Williams would be reunited with Mike Martz in Chicago. It had been reported that an agreement between the two sides was reached, but as a released player Williams and the Bears can't begin talks until Friday afternoon. Martz coached Williams in Detroit and now serves as Chicago's offensive coordinator.

The Bears are offering up tight end Greg Olsen in a trade, according to agent Drew Rosenhaus. Rosenhaus sent a mass email to the league's general managers and personnel people on Wednesday night announcing the Bears were making Olsen available for trade. "The Bears have granted me permission to seek a trade for Greg Olsen," Rosenhaus wrote. "Please let me know if interested. Sounds like the Bears will be very reasonable on the compensation in return for Greg." But 11 minutes later, Rosenhaus sent another mass email to the same recipients, asking them to ignore his previous message. "Please disregard my previous email regarding Greg Olsen," the one-sentence email said.

The Bears won't be major players in free agency, but sources say the team has a legitimate interest in Jets receiver Brad Smith. A fourth-round pick in 2006 and former quarterback at Missouri, Smith caught just four passes last season for 44 yards with no touchdowns, and rushed for 299 yards on 38 attempts. Throughout his five-year career, Smith has contributed at several positions on offense and in the return game.

Bears quarterback Jay Cutler has called off his engagement with reality television star Kristin Cavallari after just 10 months together, according to a report. "She got dumped," a source told People. "She's absolutely devastated. She can't believe this is happening." The couple, who were planning a spring wedding, became engaged in April, when Cutler proposed in Mexico. Cavallari had planned to move to Chicago during the upcoming football season.

Bears running back Matt Forte is expected to soon seek a contract extension in the wake of his above-average production. Forte is ranked fifth in the NFL in yards from scrimmage (4,731) since 2008, he joined Walter Payton as the only Bears to notch 1,000 rushing yards and 500 receiving yards in the same season and accumulated 1,400-plus yards from scrimmage in each of his first three seasons, the only player in franchise history to accomplish such a feat. "Any time a player has been producing very well," Forte said, "they're going to come back and say, 'Hey, throw me a bone here.'"

For the first time in 45 years, there will be no Hall of Fame preseason game. It's much more than just a lost preseason game for the Canton, Ohio community. The labor dispute between NFL owners and players forced the league to call off the annual Hall of Fame game between Chicago and St. Louis scheduled for Aug. 7. It's a financial blow to the Hall of Fame, which could lose about $1.5 million out of its $20 million annual operating budget. And it's a big loss for the community, which gets more than just a financial boost from the event. "We're such a football community," said Joanne Murray, director of the Hall of Fame festival for the local Chamber of Commerce. "From the staff to the man on the street, I doubt you'd find a single person who would say they're not disappointed. "We're just going to have to get through this unusual year and embrace the other events."

Bears safety Chris Harris has been working out with former teammate Steve Smith of the Panthers during the lockout. Harris has also been working to try and recruit Smith. Smith went to the home of Panthers owner Jerry Richardson late last season and asked to be traded, according to the Charlotte Observer. Harris, who played with Smith in Carolina for three seasons, thinks if the Bears could somehow acquire Smith, it would make sense. "If the opportunity is there, why not?" Harris said Thursday on "The Waddle & Silvy Show" on ESPN 1000. "You can never have enough big-time playmakers on your team. "We have plenty of those on our team now. It definitely wouldn't hurt to have another one."
