Celtic 2 Rangers 1

[Beefy]

Celtic's Jan Vennegoor of Hesselink scored an injury-time header to narrow the gap on Rangers to one point.

Shunsuke Nakamura fired Celtic ahead with a wonderful swerving shot, while Nacho Novo's strike levelled.

Carlos Cuellar was sent off for handling a net-bound Nakamura shot but the injured Allan McGregor was able to save Scott McDonald's spot-kick.

But the Celtic striker struck late on, while David Weir and Gary Caldwell saw red cards after a full-time melee.

A tumultuous evening ended with an ugly scuffle involving several players and Scotland colleagues Weir and Caldwell appeared to exchange blows.
