Coach Pete Carroll said Wednesday that Lynch "had a really good week" and is on track to play Thursday in San Francisco, Liz Matthews of 910 ESPN Seattle reports. Carroll has expressed optimism with regard to Lynch's ability to suit up in Week 13, and why not? He last missed a game in 2011, as he's frequently fended off injury to take the field. Meanwhile, in four of his last six matchups with the 49ers, including playoffs, he's surpassed 100 yards on the ground, while reaching the end zone on eight occasions. As a result, he remains a must-start in all formats.
