--S Michael Lewis left the game briefly in the second half with a left knee sprain. However, Lewis returned to the lineup to finish the game. Lewis led the 49ers with 11 tackles, a sack and a broken up pass that resulted in Nate Clements' interception.

--P Andy Lee, a Pro Bowl invitee last season, now ranks fifth in the NFL with a 47.0-yard average. Lee averaged 51.8 yards on six punts, all in the second half, of the 49ers' game Sunday against the Rams. Lee is ninth in the NFL with a 39.2 net average.

--TE Delanie Walker was inactive for Sunday's game with a right shoulder injury that he sustained Monday, Nov. 10, against the Arizona Cardinals.

--WR Bryant Johnson said he feels like he is returning to full strength. Johnson, who has been plagued by leg injuries this season, caught four passes for 56 yards and a touchdown on Sunday. He turned a short pass into a 42-yard gain against the Rams.

--RB DeShaun Foster played the entire fourth quarter after starter Frank Gore was removed from the lineup as a precaution. Foster gained just 17 yards on 10 carries, but he also caught two passes for 40 yards.

REPORT CARD VS. RAMS

PASSING OFFENSE: A -- Shaun Hill was perfect in the first half, as he threw for 192 yards and two touchdowns while achieving the highest first-half passer rating in club history: a perfect 158.3. Hill was not asked to do much in the second half. Bryant Johnson had one of his best days of the season, catching four passes for 56 yards and a touchdown. Vernon Davis caught a touchdown pass for the second game in a row.

RUSHING OFFENSE: C-minus -- Frank Gore rushed for 106 yards and two touchdowns, but it was not an all-around great day for the backs. Gore and DeShaun Foster each lost a fumble in the game. Also, the 49ers averaged 3.8 yards per-carry in the game. The offensive line did a strong job in the first half, but the play of everyone tailed off after the 49ers built a 32-point lead.

PASS DEFENSE: A-minus -- The 49ers allowed 295 yards passing to Rams quarterback Marc Bulger, but the defense made a lot of plays. Nate Clements and Walt Harris both recorded interceptions that the offense turned into touchdowns. The 49ers also recorded four sacks, and the 49ers increased the pressure as a whole on the quarterback.

RUSH DEFENSE: C -- Although it wasn't much of a factor in Sunday's game, the 49ers' run defense gave up too many yards. Antonio Pittman, filling in for injured Steven Jackson, rushed for 95 yards on 14 carries. The Rams ran the ball only 23 times, but they picked up eight first downs on the ground.

SPECIAL TEAMS: B-plus -- Return man Allen Rossum got the 49ers some good field position. He picked up 40 yards on two punt returns. Kicker Joe Nedney was called upon only for extra points. Andy Lee was not needed to punt in the first half, but in the second half he averaged 51.8 yards (45.3 net) on six attempts.

COACHING: A -- The 49ers had solid game plans on both sides of the ball. Offensive coordinator Mike Martz was able to use only a fraction of what he had drawn up because coach Mike Singletary ordered him to keep the ball on the ground and be conservative after the 49ers piled up a 32-point lead at halftime. Defensively, the 49ers mixed up their coverages and pass rush to make things difficult on Bulger, who attempted 53 passes.
