Johnson and LB Demorrio Williams had been involved in a training camp battle this offseason. It's been among the most intense with both players stating their case to start on Monday night.
The Chiefs coaching staff reportedly told Johnson he would be starting against the Chargers. He was running with the first team at practice on Monday along with Jovan Belcher.
Belcher has been in the game whenever DJ is so we're assuming Belcher will be given the starting nod as well.
Meanwhile it was Casey Wiegmann lining up at the first team center. Considering this is now a game week, and you probably want your starters working together, it could be a good bet Wiegmann is starting as well.
If that's the case, then the only other position battle we're really waiting on is at fullback, where Tim Castille is currently listed on the first team and Mike Cox on the second team.
Starting right tackle Ryan O'Callaghan is currently injured and not practicing so if he can't go on Monday night it would be Barry Richardson taking his spot. After that, the Chiefs wouldn't have any other backup tackles.
