"It does not look to be a long-term sprain," Harbaugh said of Cody. "It could be this week, but more likely it will be a couple weeks."

Backup running back Shaun Draughn suffered a high ankle sprain and linebacker Albert McClellan has a minor hip injury.

Draughn told The Baltimore Sun that the injury initially doesn't seem that serious.

"The pain was moving around," Draughn said. "It don't feel too bad right now. I think I'll be back next week, I'll be good."

Tucker rebounds

One week after misfiring twice on field goal attempts against the Cleveland Browns, Ravens kicker Justin Tucker regained his usual form by connecting on three field goals with no misses against the Texans.

Tucker converted field goals from 28, 45 and 43 yards.

"We've got a really good thing going altogether as a team," said Tucker, who hit 30 of 33 field goals last season as a rookie. "To be able to contribute the way I know I should, putting points on the board, is a much better feeling than last week. It's definitely good to bounce back."

Harbaugh said he wasn't concerned that Tucker would dwell on the rough game.

"Tucker's a rock-solid guy," Harbaugh said. "He doesn't let things bother him too much. I think he's really confident."


The Ravens were flagged 10 times for 87 yards with only two assessed after halftime.

In the first quarter, the Ravens were even hit with an illegal substitution penalty when they had 12 men on the field.

"That was a mistake on our part," Harbaugh said. "Another player thought he was replacing that guy and we got stuck with 12 on the field. If I had seen it soon enough, I would've called timeout."

Plus, offensive tackle Bryant McKinnie was penalized twice for facemask infractions.

"Sometimes against a good front, that stuff comes up, but we don't need to do that," Harbaugh said. "Our offensive line is too good to have to resort to those technique issues. We talked about it at halftime. The guys did a good job of cleaning that up."

Rice sidelined

Pro Bowl running back Ray Rice missed his first game since his rookie season, ending a streak of 66 consecutive games as Bernard Pierce replaced him in the starting lineup. Rice had started the previous 43 games, the longest active starting streak in the NFL by a running back.

Rice is dealing with a strained left hip flexor and the team is upbeat about his chances to return next week from an injury that usually takes one to two weeks to recover from.

When asked if he thinks Rice will return next Sunday against the Buffalo Bills, Pierce replied: "Hopefully. If not, it's going to be another long game."

Spears starts

With defensive end Chris Canty out with a strained groin, veteran Marcus Spears started in his place and finished with three tackles, two for losses.

Spears also started the season-opener against the Denver Broncos when Arthur Jones was out with an irregular heartbeat.

"You make a couple of standout plays and people think it's a great game, but it's never as bad or as good as people think," Spears said. "I try to keep that mentality and do my job."

End zone

Cornerback Chykie Brown played despite a right knee injury that limited him in practice all week, saying he didn't have a setback. "I think I did good with my knee," he said. "It's getting better." ... The Ravens also scratched inside linebacker Arthur Brown (strained left pectoral), center Ryan Jensen (foot surgery), wide receiver Deonte Thompson (left foot sprain) and defensive tackle Brandon Williams (right big toe). "It's not that bad," Arthur Brown said. "I don't need surgery. I don't think I'll even be out a month."
