Pittsburgh Steelers tight ends coach James Daniel allegedly verbally abused a Patriots fan in a halftime incident Thursday that also might have gotten physical.
The NFL is currently looking into the matter, NFL Media Insider Ian Rapoport reported. The incident happened upstairs at Gillette Stadium in Foxborough, and was witnessed by police.
The depth of the confrontation is still not known.
"We were informed by NFL Security and are looking into it," the Steelers said in a statement.
Daniel, 62, has been a member of the Steelers' staff since 2004.
