North Carolina suspends four players in hazing investigation
He did not specify the reason for the suspensions or whether they were connected to the report of a group assault of Tar Heels walk-on wide receiver Jackson Boyer during fall camp at the team's hotel that resulted in an alleged concussion. Fedora also said he wasn't certain the university's internal investigation was completed.
"We're going to hold all of our guys accountable for everything they do on the field and off the field," Fedora said. "We also have very high expectations for our guys in this program and they didn't meet those expectations."
Walker had 21 tackles and one interception while appearing in all 13 games last season. Lawrence had 11 tackles in eight games.
According to the Yahoo Sports report, during the first week of August, Boyer was involved in a physical altercation with multiple teammates in his hotel that left the redshirt walk-on concussed.
This is the latest in a series of scandals that have plagued UNC in recent years, including a recently reopened investigation into academic misconduct.
Earlier Tuesday, there were reports that defensive lineman Ethan Farmer could have an academic eligibility issue.
