Tomorrow's night game between the Pittsburgh Steelers and Baltimore Ravens has been postponed due to an outbreak on the Ravens. This will be the first time since 2005 that there will be no primetime NFL game on Thanksgiving. The battle between the 10-0 Steelers and 6-4 Ravens was the best game on a Thanksgiving Day where all the other games are between losing teams. UPDATE: NBC will air Steelers-Ravens nationally Sunday at 1:15 p.m. ET against CBS and Fox's traditional slate of NFL games. NBC will have Al Michaels, who was scheduled to have Thanksgiving and Sunday off, call the Steelers-Ravens game. Mike Tirico, who was scheduled to call the Ravens-Steelers game and the Packers-Bears game on Sunday, will just call the Packers-Bears game.
