Following Memorial Day Weekend, the Buffalo Bills are back inside One Bills Drive for the start of voluntary Organized Team Activities (OTAs).
Tuesday marked the first day of the OTA period and head coach Sean McDermott spoke to the media ahead of practice. Here are five things we learned.
### **Attendance check**
While the OTA phase of the offseason is not mandatory, McDermott reported strong attendance numbers for the team. All members of the active roster have reported for the week, except for RB James Cook.
"We're staying in touch like you'd expect a player and a coach to do. James will be here when he's ready to be here and we move forward," McDermott shared.
The Bills will lean on RBs Ty Johnson, second-year player Ray Davis and others in practice while Cook is absent.
### **Bosa to miss OTAs with calf injury**
One of the Bills free agent additions to their defense is dealing with an injury and will not be practicing with the team this week. DE Joey Bosa, who signed a one-year deal in March, will be sidelined with a calf injury.
McDermott explained Bosa "pulled a calf" late last week before the holiday weekend while participating in offseason workouts at the facility. Bosa will be out for the "foreseeable springtime" but the edge rusher "should be good to go for training camp".
The head coach added that because the injury popped up so recently, the medical staff is still gathering information on what the full timeline will be.
"Joey was off to a good start before that, so it's unfortunate to see him go down," McDermott added.
