The NFC West is void of any major injuries with a quarter of the 2012 season in the books after a relatively healthy showing across the board in Week 4.
The San Francisco 49ers (3-1) were without the services of running back Brandon Jacobs and defensive tackle Isaac Sopoaga Sunday after as both sat with knee injuries but other than that, there weren't any setbacks to speak of. Continuing with the good news, wide receiver Ted Ginn Jr. finally returned from his ankle injury and made his 2012 season debut by fielding four punts.
The Arizona Cardinals (4-0) also dodged any major injury bullets Sunday as the team had no new ailments to report. Defensive tackle Darnell Dockett (hamstring), tight end Todd Heap (knee) and reserve running back LaRod Stephens-Howling (hip) were all inactive but it wouldn't be surprising if they returned on the short week with the Cardinals heading the St. Louis on Thursday.
Speaking of the Rams (2-2), St. Louis lost reserve defensive end Eugene Sims to a head injury in their 19-13 win over the Seattle Seahawks (2-2). Sims did not return after the occurrence in the second half and some are speculating that it might be concussion due to the nature of the injury. Defensive tackle Michael Brockers also left briefly with an ankle injury but was able to return and gut it out.
As for the Seahawks, Seattle suffered a slight scare Sunday when left guard James Carpenter left the game with a knee injury after missing the first three games of the season because of that issue. Fortunately, Carpenter left under his own power and was able to return less than a quarter later.
