The Chargers list LB Kenneth Murray Jr. (shoulder) as doubtful for Sunday's game against the Chiefs. Nick Niemann started in his place last week and delivered 11 tackles (6 solo, 1 for loss). He did so on just 68% playing time, though. So be careful about overrating Niemann for Week 18 IDP use -- especially against a very different version of the Chiefs offense than we usually see. Check our Week 18 LB rankings to see where Niemann lands.
