NFL Media Insider Ian Rapoport made the revelation although the four teams were unnamed in his July 10 report:
"Before OTAs and minicamp, star wide receiver Andre Johnson told the Houston Texans he had heard enough from the new staff and coach Bill O'Brien to make him want to show up and join the team. He told them of his plans to be there for offseason workouts, despite missing the early portion of it. The question revolved around his $1 million bonus for attending workouts.
"Though Johnson had missed some of the sessions, he wanted to earn his money back by working out extra, allowing him to receive the money.
"The Texans told him no, per two sources informed of the situation.
"That furthered the divide between Johnson and the Texans, driving a wedge between the parties. That caused Johnson to tell them he wanted to play for another team. He is now working out,'not thinking about the Texans,' a source said.
"The Texans have not yet been willing to trade him.
"As he has expressed publicly, Johnson believes the team is rebuilding, and he has said he has doubts about if he wants to take part in another similar process, as he has several times in his career.
"Johnson has also restructured his contract in each of the past three years at the team's behest, and he wants the same goodwill from the Texans regarding his $1 million roster bonus that he could earn in Week 1 if he participates in offseason workouts and fulfill his contract.
"The Texans declined to comment on the story, and Johnson's agent, Kennard McGuire, did not return a call for a comment. Johnson told NFL Media on Wednesday that he didn't know if he'll be with the Texans on Week 1. Asked if he'd be at camp, Johnson said 'hopefully' but he didn't know for sure.
"Johnson is said to earn $10 million this year, not including his workout bonus.
"The Texans have resisted his request for a trade thus far, though four teams have expressed interest. Meanwhile, one veteran Texans player said while the team wants Johnson wants to play with them in 2014, they've also told him from a business sense, 'Stick to your guns.'
"One possible option for the team to resolve this standoff (if they refuse to trade him) is to guarantee he's on the roster for 2015. That might bring Johnson back. They also could simply decide to pay him his $1 million bonus. Or, they could stand their ground and he'll play for no one in 2014."

In spite of Johnson's current stance, former Green Bay Packers wide receiver told CSN Houston's James Palmer on June 23 he believes Johnson will eventually return to the Texans:
"Former Green Bay Packers wide receiver Donald Driver believes Andre Johnson will be in a Texans uniform this season.
"Driver held a youth football camp in his hometown of Houston on Monday. Driver still spends time in Houston and still follows the Texans closely. The retired wideout knows Johnson's current situation because he's gone through it himself.
"'I've been through the same situation Andre's in,' Driver said. 'You feel like you want more. Normally, the organization knows what they want and the player knows what they want. Sometimes you have to meet in the middle. I think sooner or later they're going to meet in the middle and Andre is going to be back at camp.'
"Johnson said on May 13 that he was questioning if Houston was still the place for him to play football. It was back on that day, when the 11-year vet, who's played his entire career for the Texans, said he was not going to attend OTAs and mandatory minicamp.
"Driver, who played 14 seasons, also just for one team, said the practices Johnson opted to miss are not all that important.
"'As long as he's here for training camp, I guess that's the biggest thing,' Driver said. 'You know these minicaps and OTAs, do they really matter at the end of the day? No. As long as he's here for training camp when the season is starting and is getting ready to kick off. Andre will be back. It's just one of those things; it's a business decision that we all have to deal with. It's unfortunate.'
"Driver believes Johnson will be back with the Texans because Houston doesn't have many options if they decided to take the field without No. 80 this season.
"'Andre is here,' Driver said. 'He isn't going anywere. He's made the team what it is and if you lose one of those guys, where are you going from there? You only go downhill. One of the things is, they don't have any one to replace him at this point. He's still one of the top receivers in the game so you got to give him credit.'"
The 32-year-old Johnson is entering his 12th NFL season -- all with the Texans -- and has amassed 12,661 receiving yards and 61 touchdowns on 927 receptions in 154 career regular-season games, per ESPN stats.
