Texans backup quarterback Rex Grossman will miss about a month of action with a hamstring injury. Houston is looking for another quarterback to fill in until the former Bears starter in healthy. Grossman was injured in Saturday's win over the Chiefs and coach Gary Kubiak says he doesn't feel comfortable finishing the preseason with only Matt Schaub and backup Dan Orlovsky.

Texans rookie linebacker Brian Cushing won't play in the team's first preseason game because of a left knee injury. Cushing did not practice on Wednesday. "I just know that we're in an evaluation process right now and we're not going to know anything for a few days," coach Gary Kubiak said. "But he's going to miss some time."

Rex Grossman likely will begin the season behind Matt Schaub and Dan Orlovsky on the Texans' quarterback depth chart, and while he won't like not playing, this year might end up serving a purpose. ?I felt like this is a good offense, a chance to learn and revive my career and get going and have a fresh start,? Grossman said.

Brian Cushing, the Texans' first-round draft choice, has agreed to a contract. Cushing, the 15th pick in the first round, is in Los Angeles and hoping to join the Texans at training camp on Saturday. Cushing, 6-3, 262, was inserted as a starter on the strong side the first time he stepped on the field at the organized team activities.
