The Texans made it official Saturday, placing quarterback Tom Savage on injured reserve in the wake of a major concussion he suffered against the San Francisco 49ers on a hit from outside linebacker Elvis Dumervil.

A joint NFL-NFL Players Association investigation remains ongoing into whether the Texans and medical personnel and spotters properly handled the NFL concussion protocol when Savage was allowed to go back into the game briefly before being rechecked and then ruled out for the remainder of the game.

A former fourth-round draft pick from Pitt, Savage is a pending unrestricted free agent who remains under the NFL concussion protocol weeks after a scary head injury that left him lying on the ground with his arms and hands twitching.

Savage started a career-high seven games this season, completing 58.1 percent of his throws for 1,412 yards, five touchdowns and six interceptions for a 71.4 passer rating.

The Texans replaced Savage at halftime of the season opener with rookie Deshaun Watson, who excelled until he tore his anterior cruciate ligament.

Savage had his moments this season and figures to have a solid future as, at least, a reliable backup and spot starter.

Savage passed for a career-high 365 yards in a loss to the Tennessee Titans.

The biggest problem Savage had this season other than his health was a tendency to fumble behind a suspect offensive line. He lost seven fumbles this season.

The Texans promoted former Virginia Tech tight end Ryan Malleck from the practice squad to the active roster to take over Savage's spot.
