NFL notebook: Vikings RB Peterson steps up regimen after knee surgery
Vikings running back Adrian Peterson is moving forward in the recovery from surgery on his right knee.
Peterson was ran short sprints in the team's indoor facility Tuesday while the athletic training staff supervised and his teammates went through practice on the field. With five games remaining in the regular season, there's no timetable for Peterson's return, but the four-time All-Pro pick could be ready some time in December.
Coach Mike Zimmer consistently has refused to entertain any speculation about whether the Vikings might have the franchise's all-time leading rusher in the backfield again this year, but when pressed on the topic by reporters he acknowledged Peterson was “probably ahead of schedule” in his rehabilitation. Zimmer said the running session, which took place during the portion of practice that was open to the media, was not the first for Peterson.
The Vikings (6-5) are last in the NFL in rushing with 71.1 yards per game and 2.8 yards per attempt.
RG III cleared to play
Browns quarterback Robert Griffin III cleared the final medical hurdle in his comeback.
Coach Hue Jackson must decide whether to reinsert him into the starting lineup.
With the Browns 0-12 and Jackson hoping to avoid a winless season, it presumably would be a no-brainer for him to test whether Griffin can breathe life into an offense that has produced just 39 points in the past four games.
Bills OT suspended
The NFL suspended Bills offensive tackle Seantrel Henderson for 10 games for what the player's agent said stems from his client using marijuana to relieve the effects of Crohn's disease.
The Bills announced the league notified them of Henderson's suspension for violating the league's substance abuse policy. It is Henderson's second suspension this year after he served a four-game ban to start the season.
Henderson's agent, Brian Fettner, called the league's decision “heart breaking” and added he cannot appeal the suspension because the NFL doesn't allow an exemption for medical marijuana use.
