Warren Sapp should have gone to sleep. The 42-year-old Hall of Fame defensive tackle, who was covering the Super Bowl for NFL Network, was arrested early Monday at a hotel in Phoenix for soliciting a prostitute — around 7 a.m., according to TMZ. In addition to solicitation, Sapp also was arrested for assault. NFL Network suspended Sapp indefinitely, without pay, pending the outcome of the investigation, a network spokesperson said.
