I would sit on him. He's the 3rd leading rusher in the NFL, and he's gone against some tough rush defenses (Was, SF). Green Bay shut down AP tonight, so they aren't slouches either.
On yards alone, he's been a top 15 RB in PPR leagues with ZERO touchdowns. He's got a tough match-up next week (Minnesota), but after that it's a cake walk: Jacksonville, Indianapolis, and Detroit all in a row.
If your goal is to trade him, it should be around that time. As of now, you're likely the person in the trade who will get burned because Jackson isn't going to go touchdown-less for much longer.
