But Hal, who started all 16 games at free safety last season, recently was diagnosed with Hodgkin’s Lymphoma. He still is being evaluated at MD Anderson Cancer Center to determine his course of treatment.
While he vows to play again, Hal won’t start the season on the field with the Texans.
The Texans will have only five healthy safeties at their minicamp this week, with Mathieu, Justin Reid, Kurtis Drummond, Treston Decoud and Ibraheim Campbell getting reps there. Corey Moore continues to rehab an injury that will keep him out until training camp.
Jackson has played safety in practice and in games, with his versatility an asset for defensive coordinator Romeo Crennel.
The best-case scenario for the Texans would be for Justin Reid, a third-round pick out of Stanford, to win the starting job in training camp.
