Bill O'Brien unsure of Andre Johnson attendance

Bill O'Brien has admitted that he does not know whether Andre Johnson will be attending the Houston Texans' mandatory minicamp next week.

The wide receiver has been absent from organised team activities this off-season after hinting that he was keen to leave the team, who finished with the worst record in the league in 2013.

The head coach told reporters: "You know, again, I don't know. I don't know."

The 32-year-old has three seasons remaining on his contract with the AFC South side.
