NFL Media Insider Ian Rapoport reported, per a source informed of Johnson's whereabouts, that the star wide receiver has been at the Texans' facility several times this offseason.
Johnson did not meet with team officials, however. His presence at football headquarters has no bearing on whether he will show for the beginning of training camp, a source tells Rapoport.
In other words, Johnson's mindset has not changed, and there has been no decision about re-joining teammates later this week.
It's a positive sign for Texans fans that Johnson is diligent enough to learn the offense while squaring off with the organization in a business dispute.
