Crusaders displayed their title credentials with a battling comeback victory over derby rivals Cliftonville at Solitude on Saturday. Three days later and the leaders face another major test - overcoming a Coleraine side that has not tasted defeat in 17 games. Linfield are hot on their heels, one point back and with a Windsor Park encounter against Glenavon. However, games are running out for Blues with just two left after tonight.  

At the opposite end of the table the scenario is simple for basement boys Portadown. Anything less than a win at Ards and defeat for second-from-bottom Carrick Rangers, who host Glentoran, will see the Ports relegated. Dungannon Swifts will be determined to stay in seventh, the final Europa League play-off position, as they visit Ballinamallard while Ballymena United are aiming for a first win in six games when they enterain Cliftonville.

So a busy evening of Premiership action ahead and we've got all angles covered. Tweet us at @BBCSPORTNI, external with your thoughts on what could be a decisive night at the top and bottom of the league.
