Matt Schaub and Andre Johnson had a heated exchange during the Houston Texans' 28-23 loss to the Oakland Raiders.

Schaub's end-zone pass to Johnson was thrown into safety Usama Young's hands with the game on the line.

Johnson yelled at Schaub, who in part screamed back. Johnson left the field as the Raiders knelt to end the game.

"It's just frustration. It doesn't bother me that players get mad," Kubiak said. "Hell, I hope guys get mad when things aren't going well. But we've got to handle it; them two will handle it."

Arian Foster has been placed on injured reserve as he will undergo season-ending back surgery.

Foster's injury was suffered during training camp and became an issue again recently.

Foster had 121 carries for 542 yards and one touchdown this season.

The Houston Texans have released Ed Reed.

Reed signed with the Texans this offseason after a long career with the Baltimore Ravens.

Reed is contemplating retirement.

Gary Kubiak made a surprise appearance at Houston Texans' practice on Thursday.

Kubiak spoke with the players and was upbeat just a few days after collapsing on the field.

Kubiak is expected to return to the Texans' sideline next week.

Gary Kubiak has been cleared to leave the hospital following a mini-stroke on Sunday when he collapsed at halftime of the Houston Texans' game against the Indianapolis Colts.

Kubiak said in a statement that he's expected to make "a full recovery."

“I want to thank my family, the McNair family, the Texans organization, the doctors and staff at Houston Methodist and the entire Houston community for all the love and support we have received over the past three days," Kubiak said. "I've been through an ordeal and my focus now is to get back to good health. Doctors have told me I will make a full recovery but we have not determined when I will be cleared to return to the office. Again, thank you for the support and concern.”

Kubiak is expected to miss this week's game against the Arizona Cardinals, but return to the sidelines the following week.
