Lawton had a 24 game injury sometime during the season, but I went back well beyond that and never saw him listed in a box score.
As far as Jenkins, he's had most of the previous 2 weeks (at least) off, and is still at 110% use.

It could be just as likely that the manager has abandoned the team, and his last set of lineups were when he was trying to rest Jenkins and when Lawton was still injured.

If that "benefit of the doubt" doesn't turn out to be fact, then "tanking" could be a consideration.

Maybe you could notify Mike and have him check on possible inactivity, though I'm not sure how much inactivity the Commish will deem important enough to "step in". For understandable reasons, they really don't like to do it....

"Inactivity" happens a fair amount I've noticed. It appears that my next opponent in one of my leagues has already abandoned his team, as he has still-overused guys that have already been "rested" for over 25 games, and the sad part is that we only just completed our 60th game of the season !
