Revisiting the Pittsburgh Steelers' 23-20 win at the Indianapolis Colts:

The Steelers' struggling offensive line is beginning to break down just three weeks into the season.

Three starters -- left tackle Jonathan Scott, right guard Doug Legursky and right tackle Marcus Gilbert -- left the game with injuries, and their availability is uncertain for Sunday's game at Houston. The injury to Scott, who was beaten repeatedly by Colts defensive end Dwight Freeney, looks to be the most serious.

Pittsburgh coach Mike Tomlin didn't provide an update after the game and wouldn't specify the injury to Scott. "I don't know what it is," he said. "I am not going to speculate."

It appeared as if Scott sprained his ankle. Gilbert hurt his shoulder, and Legursky separated his shoulder. Because the Steelers only suited up seven offensive linemen, Gilbert had to return to the game when Scott had to be helped off the field.

If Gilbert and Legursky are sidelined, the Steelers would start Ramon Foster at right guard and Trai Essex at right tackle.

To address left tackle, the Steelers might have to reach out to Flozell Adams or Max Starks, both of whom were released by the team at the end of July. Adams, a left tackle who switched to the right side for Pittsburgh last season, would seem to be the preferable option to the team because the Steelers have remained in contact with him.

STAT THAT STICKS: 27 -- Game-winning drives in the fourth quarter that Ben Roethlisberger has delivered (which includes playoffs) in eight NFL seasons.

OVERHEARD: "We walked out of here with a win. Did we play well? No, we know we didn't play well. Do we got to get better? Yes, and we will get better." Steelers wide receiver Hines Ward on the tougher-than-expected win at Indianapolis.

LOOKING AHEAD: The Steelers (2-1) play at the Texans (2-1), who are coming off their first loss of the season (a 40-33 defeat at New Orleans).
