Mostert (thumb) isn't practicing Wednesday, David Furones of the South Florida Sun Sentinel reports.
Mostert's absence to begin the week of practice was fully expected after head coach Mike McDaniel said the running back suffered a "significant break" to his thumb in the fourth quarter of Sunday's 11-6 win over the Jets. Backfield mate Jeff Wilson could see a larger share of the workload than usual even if Mostert ends up playing, as the thumb fracture will impact his ability to catch passes at the very least.
