Irish Premiership: Crues and Blues in top-two stalemate
It's as you were at the Premiership summit as leaders Crusaders and Linfield failed to find the net in a disappointing Windsor Park draw.
Both sides hit the woodwork and Crues boss Stephen Baxter was sent-off in a feisty finish but his side remain four points clear of the Blues.
Cliftonville beat Glenavon 3-0 to go third while Portadown came from behind to secure a 3-1 win over Ards.
Ballymena hammered Ballinamallard 4-0 and Glentoran beat Carrick 2-1.
It was the second scoreless draw between the Crues and Blues this season with an ill-tempered climax providing the main drama in a game of few openings.
Crues midfielder Jordan Forsythe smashed his shot against the bar and it was the same outcome for Linfield from Ross Gaynor's mishit cross.
The best chance of the second half fell to the visitors but Gavin Whyte sliced his volley high and wide when well placed.
Paul Heatley's heavy challenge on Andrew Waterworth sparked a flurry of yellow cards late in the game while Baxter's protests resulted in his dismissal from the touchline.
Cliftonville moved to within five points of the champions thanks to second-half goals from Jason McGuinness, Ruairi Harkin and David McDaid at Solitude.
Johnny McMurray bagged a double as Ballymena responded to two straight defeats by brushing the Mallards aside at the Showgrounds.
Three in a row
It's all going sweetly for new Glens boss Gary Haveron as his team chalked up a third successive league victory.
Haveron was up against his former club at the Belfast Loughshore Arena and goals from Steven Gordon and Curtis Allen put the Glens 2-0 ahead before Paddy McNally pulled one back for Carrick.
Portadown have left the minus points column with an impressive fightback after Michael Ruddy's penalty opener for Ards.
Robert Garrett, Stephen Hughes and Brendan Shannon (penalty) were on target as the Ports closed the gap on second-bottom Carrick to five points.
