49ers head coach Mike Singletary had to separate tight end Vernon Davis and wide receiver Michael Crabtree after the players got into a heated discussion at practice Wednesday, according to an ESPN.com report.
Singletary didn't provide details about the incident, but said it was non-football related and is closed. He met with both players immediately in the locker room and they returned to practice separately.
