Police have interviewed 49ers wide receiver Michael Crabtree over allegations that he sexually assaulted a woman last week, reports the San Francisco Chronicle. The 25-year-old has not been charged and is expected to play tomorrow against Atlanta in the NFC championship. The alleged assault occurred at a hotel after last week's victory over Green Bay. "The 49ers take such matters very seriously," said a team statement. "We will have no further comment at this time as the legal process is ongoing."
