(WNFL) - Both the Green Bay Packers and Pittsburgh Steelers were not happy with the major calls that went against them in yesterday's 38-31 Steeler victory. In the third quarter, referee Carl Cheffers awarded the Packers the ball after the Steelers blocked Mason Crosby's field goal attempt -- and Steelers' lineman Ziggy Hood slapped it out of bounds. Meanwhile, the Packers had 10 seconds tick off the clock in the final moments, after right tackle Don Barclay had a false start penalty called on him with no time outs left. Green Bay linebacker A-J Hawk said Cheffers told quarterback Matt Flynn just before he was about to snap the ball that the clock was running -- and it could have thrown off the Packers' timing on their final play, a pass in the end zone which went incomplete. After the blocked field goal, a long conference followed -- and Cheffers ruled that Pittsburgh got a five-yard penalty for slapping the ball forward out of bounds, thus giving Green Bay another first-and-goal situation. Steelers' coach Mike Tomlin said certain that a Steeler had recovered the ball on its way out of bounds, something Cheffers said didn't happen. Tomlin wanted the play reviewed, but the referee it was not reviewable under the rules. The Packers' loss still sets up a showdown at Chicago next Sunday, with the winner clinching the N-F-C North title and a playoff berth.
