Miller said he suffered a minor quad injury during Sunday's loss to the Chargers, but head coach Dan Campbell said the issue was unrelated to Miller's absence in the second half, Andrew Abramson of the Palm Beach Post reports.

With Miller off to a slow start and the entire team struggling, Jay Ajayi and Damien Williams took over in the second half. It was an odd decision if it really had nothing to do with Miller's health, given that he's been very effective as both a runner and pass-catcher this season. He did enter the game with a minor ankle concern, which may have contributed to his poor showing in the first half. Despite what transpired Sunday afternoon, Miller figures to lead the Miami backfield in Week 16 against the Colts, assuming he's healthy enough to play. Of course, even when he dominates the snaps, Miller's workload is difficult to predict in any given week.
