Gregory barred from Cowboys practice

Updated: 

Second-year defensive end Randy Gregory is not just suspended from playing for the Dallas Cowboys on Sundays, he cannot even step on the practice field.

Gregory is currently serving a suspension that runs through to Week 15. However, he applied for a two-week practice exemption in the hope of getting up to speed before his return.

The NFL promptly denied Gregory's request.

A second-round draft pick from Nebraska a year ago, Gregory was initially suspended for the first four weeks of the season for violating the league's substance-abuse policy. But another violation added on an extra 10 games in late September.

The Cowboys have surged to an 11-1 record this season, but their pass rush is lacking with just 23 sacks. Gregory could certainly help there, but will not be in action until Week 16 against the Detroit Lions at the earliest.
