Special teams struggled: The Texans didn't get much from their special-teams units once again. It started with a missed 45-yard field goal by Randy Bullock that could have cut the 49ers' lead to 7-3. Instead, San Francisco maintained a shutout until the third quarter. Returner Keshawn Martin made some questionable decisions on when to bring the ball out of the end zone, seemingly pressing to make a big play. The Texans allowed a kickoff return of 29 yards and two punt returns for a combined 28 yards. Martin also suffered a shoulder injury for which he was scheduled to have an MRI on Monday.
More on the injury front: Left tackle Duane Brown seemed to have come out of the game in good shape injury-wise after working through a case of turf toe that he suffered against the Tennessee Titans. But safety Ed Reed came up hobbling after stopping a sliding Colin Kaepernick. Reed said after the game that he tweaked his knee on the end of the play, not the hip on which he had arthroscopic surgery in April. Reed also said he wasn't concerned about the injury and it did not need further tests Monday.
Run defense: I'll repeat my thought from Sunday night that you cannot blame the loss on the Texans defense. It is worth noting, though, that the rushing defense was gashed by San Francisco. The Texans gave up 177 rushing yards, 81 of them to Frank Gore, an underrated talent who has worked through injuries for a lot of his career. (Side note: Gore was one of the former University of Miami teammates that Reed talked about wanting to reunite with in free agency. Andre Johnson, Reggie Wayne and Gore.) The 49ers averaged 4.9 yards per carry and Kaepernick only ran the ball once. That's 0.7 yards per carry more than the Texans went into the game giving up. According to ESPN Stats & Information, the 49ers gained 118 of their 177 rushing yards before contact.
On the other hand: It was for naught, but given the situation Arian Foster might have played his best game of the season. Before the game, a group of 49ers fans heckled him by saying he wouldn't have a 100-yard performance. Foster almost got there, rushing for 98 yards. But he did it on only 21 attempts for a 4.7 average, a mark well above his 3.8 yards per carry entering Sunday night.
