Texans cornerback Kevin Johnson broke his foot against the Indianapolis Colts on Sunday night, according to sources not authorized to speak publicly.

It's feared this could be a season-ending injury. Johnson got X-rays after the game to confirm the initial diagnosis.

Johnson played through the injury as he only missed one snap during the game, but was limping badly afterward at NRG Stadium.

A first-round draft pick from Wake Forest last season, Johnson started at left corner during the 26-23 overtime win. He was extremely effective against Colts wide receiver Phillip Dorsett.

This represents a major blow to the Texans' secondary with the loss of such a talented, young player. The Texans are already dealing with injuries to veteran cornerbacks Johnathan Joseph (forearm) and Kareem Jackson (hamstring).

Joseph played through the injury one week after dealing with a concussion that sidelined him against the Minnesota Vikings. Jackson missed his second consecutive game, but could return for the Texans' game against the Denver Broncos.
