Rice caught three passes and ran for 36 yards on 13 carries before leaving. He did not undergo an MRI on the injury, though, and Harbaugh said on Monday that he would probably rest Rice in practice this week and then see how he is on the weekend.
"That's the indication, that it's not anything that's really serious," said the Ravens coach. "They would be looking at it if they thought it was. So, we'll just be day-to-day with him."
Quarterback Joe Flacco was on the field Sunday despite his wife giving birth to the couple's second child hours earlier and helped the Ravens rally from a 6-0 halftime deficit. He threw for 211 yards, including a five-yard TD pass to wide receiver Marlon Brown in the fourth quarter.
He completed third-down passes of 16 and 18 yards on Baltimore's last scoring drive.
"Anytime you have a child, it's one of your best days," Flacco said afterwards. "The game didn't go exactly how we wanted it to, but that's how we've won football games around here. We're able to win like this, and sometimes you have to do it in an ugly way."
Following a 49-27 rout at the hands of Denver to begin the season, the Ravens avoided their first 0-2 start since 2005 under Brian Billick.
"We came into the locker room (at halftime), sat down and said we have to get it together and get this running game going. Because once the running game gets going, the passing game gets going," said Ravens back Bernard Pierce, who ran for a five-yard score in the third quarter.
"We took a deep breath, got it together and went back out there and made plays."
The Ravens won each of their first five regular-season games against the Texans franchise before Houston managed a 43-13 on Oct. 21 of last year. Foster ran for 98 yards and scored twice, while Schaub threw for 256 yards with a pair of touchdowns.
Flacco was held to 147 yards passing, was sacked four times and picked off twice.
The Ravens have won both of their regular-season games at home versus the Texans and also secured a victory over Houston in Baltimore during the playoffs on Jan 15, 2012 to end the Texans' first trip to the postseason.
Reed had a late interception in the game to help seal the win for the Ravens.
WHAT TO WATCH FOR
After a decade of having Reed on their side, the Ravens for the first time will have to game plan around the star safety. Harbaugh said that will be difficult to do given that Reed has yet to play this season for the Texans.
"It's a little tougher because we haven't seen him on tape, so we really don't know how he fits in their defense. We'll have to fit him into their scheme, which in a lot of ways is similar to what we've done here. So, it shouldn't be too hard to figure out where he's going to be and just envision him out there playing the way he played for us all those years," noted Harbaugh.
Reed may not be the player he once was, but a return to Baltimore should add some extra energy to his legs, assuming he can get on the field.
"No, there's nothing specific I'm looking for," Kubiak said in regards to what it would take to declare Reed ready to play. "I think it's a combination of everybody looking for those explosive movements from the middle of the field to the sideline, breaking on the ball. Those type of things. To where it looks the way it has in the past and the way Ed knows it's supposed to look."
Reed had to feel bad for his former teammates after they were lit up by Denver's Peyton Manning in Week 1. Baltimore gave up seven touchdown passes to Manning and 510 yards in total to the Broncos offense, but held the less- talented Browns to 259 yards while keeping the club out of the end zone.
