Good luck with whatever team you end up with DeseanJackson10!- Jason Kelce (@Jkelce) March 28, 2014
Jackson was due to make $10.5 million in 2014 and was owed $30.5 million over the remainder of his contract, but none of that money was guaranteed.
He received praise from Reid, who drafted him in the second round in 2008.
"I have nothing but good things to say about the kid," said Reid, now the coach of the Kansas City Chiefs. "I did draft him. I had a great relationship with him. When his father passed away, that was a hard thing for him to go through at a young age. They were best friends. I've experienced life things with him, so I would tell you he was great for me when I was there."
At least nine teams already have reached out to Jackson's agent, according to a league source.
Jackson is expected to visit the Washington Redskins on Monday, an NFL source confirmed to ESPN.com.
"We'd be interested. He's an intriguing player, and we'll take a look at him," Panthers coach Ron Rivera told USA Today Sports. "I just got word, and this is surprising to hear. He's an explosive player who has great vertical speed and is strong going to the ball."
However, sources told ESPN.com's David Newton that the Panthers aren't interested in Jackson for a variety of reasons.
Recent reports surfaced that the Eagles were looking to trade Jackson. There also had been rumors that Jackson isn't a fit in the locker-room culture that Kelly, entering his second season, is trying to cultivate.
At the NFL owners meetings Wednesday, Kelly said he liked Jackson but would not commit to him for 2014, saying the Eagles would do "what's best for the football team."
There may have been signs earlier in the offseason that the Eagles were looking to move on from Jackson. The team moved quickly in free agency to complete new deals with wide receivers Jeremy Maclin, coming off a torn ACL, and Riley Cooper.
Jackson's offseason also got off to an unsettling start.
After the Eagles lost in the wild-card round of the playoffs to the Saints, Jackson said he wanted to renegotiate his contract, then a few days later he told police his South Philadelphia home was robbed of more than $250,000 in cash and jewelry, along with a handgun. No arrests were made in the case. Police on Friday clarified the case, saying they mistakenly released incorrect information and Jackson was robbed of $20,000 in cash, according to the Philadelphia Inquirer.
Jackson excelled in Kelly's fast-paced offense, setting career highs in receptions (82) and yards (1,332) and while also amassing nine touchdowns. His 6,177 receiving yards are the second-most in franchise history, and his four punt-return scores are tops in club history.
Jackson also has 21 TD catches for at least 30 yards, tied with Miami's Mike Wallace for the most in the league. No other player on the Eagles' roster has more than eight (Maclin).
