Most teams haven't been on the practice field for even a week.
The Bills and other teams haven't even started hitting.
Yet, through Monday afternoon, several NFL teams have already lost key players to season-ending injuries. Unofficially, eight players have already suffered injuries which are expected to keep them out for the entire season:
Dennis Pitta, Ravens TE (hip)
Tyrone Crawford, Cowboys DL (Achilles)
Armon Binns, Dolphins WR (knee)
Jeremy Maclin, Eagles WR (knee)
Jason Phillips, Eagles LB (knee)
Turk McBride, Bears DE (Achilles)
Dan Koppen, Broncos C (knee)
Aaron Berry, NY Jets CB (knee)
On top of the season-ending injuries, just on Monday alone, teams were dealing with numerous injuries which forced players to leave practice early be evaluated by medical personnel.
In Denver, defensive tackle and first round pick Sylvester Williams hobbled off the field and into the facility after hurting his left knee midway through practice.
In Arizona. Starting guard Daryn Colledge, Linebacker Jasper Brinkley, wide receiver LaRon Byrd, and injury-plagued running back Ryan Williams all missed the Cardinals' practice with injuries.
Jacksonville Jaguars quarterback Blaine Gabbert sprained his right ankle in practice, but the team believes he could return later this week.
In Buffalo, defensive end Mario Williams missed practice and was "off campus," according to head coach Doug Marrone, being examined for a foot injury which held him out of drills on Sunday, the first day of practice.
WGR's Paul Hamilton has more on Williams' situation and Marrone's comments.
