Doesn't practice Thursday

Marks (knee) didn't practice Thursday, Chris Easterling of the Akron Beacon Journal reports.

Marks was limited Wednesday, so his 'DNP' on Thursday is concerning, though it could be more of a workload management situation, as opposed to a setback-related downgrade, a notion supported by Aaron Wilson of KPRC 2 Houston's report that the running back dealt with mild knee discomfort in Wednesday's practice and didn't finish the session for precautionary reasons. Meanwhile, fellow backfield member David Montgomery (groin) -- who hasn't played since Week 5 -- returned to a limited session Thursday. Valuable context regarding the duo's status will arrive Friday, when the Texans have their final practice before Sunday's road game against the Browns.
