Vernon didn't look totally healthy in last Thursday's game against the Rams. He scored a TD as part of his quiet two-catch, 18-yard game.
Since he gets a few extra days rest from his last game, chances are that Davis is close to 100 percent. The Texans have struggled a little in keeping tight ends in check and the possible loss of Brian Cushing could spell even bigger trouble.
Fantasy impact: Obviously, you're going to start Davis. He'll be Colin Kaepernick's favorite target and it's not surprising that Kap's production has dropped along with Davis' health. Speaking of Kap, the Texans have been vulnerable in pass D, so he should be viewed as a high-upside QB1 in fantasy leagues. Anquan Boldin shouldn't be negatively impacted since the efficiency of the O goes up, so he'll have a smaller piece of a much larger pie.
