The Kansas City Chiefs haven't made a roster move since October 26th but they're still working guys out in case they need to make one soon. According to Adam Caplan, the Chiefs worked out a pair of linebackers this week -- LB Nate Triplett and LB Caleb Campbell.
Triplett is a second year player out of the University of Minnesota and he would be shooting for a special teams roster spot. He was originally signed by the Minnesota Vikings, spent time on the San Diego Chargers practice squad and most recently was waived by the Indianapolis Colts.
Campbell spent time with the Detroit Lions and Indianapolis Colts. He was originally a seventh round pick by the Lions in the 2008 NFL draft but in a unique situation had to return to the Army to fulfill his obligations. Read more about his situation here and here.
