Hurling's second-tier swings back into action as all six teams are out again after a break last weekend.
Westmeath are sitting pretty with three wins out of three and can confirm their place in the final this weekend.
Pre-competition favourites Laois need to continue their revival or they will be out of contention.

SATURDAY
Westmeath v Antrim, TEG Cusack Park, 3pm
The two most impressive sides in the competition to date meet in Mullingar in a game that will have a big bearing on the promotion race.
Antrim's only defeat was by a single point to Laois while Westmeath have a 100% record and can guarantee a place in the final with a match to spare if they extend that streak to four games.
"This is a must-win game from our perspective, there's no other way of putting it," Antrim joint-manager Dominic McKinley told the Belfast Telegraph.
Antrim will be without injured duo Joe Maskey and Michael Armstrong.
Both sides have raised eight green flags across their opening three games so expect goals.

Westmeath: TBC
Antrim: Ryan Elliott; Arron Graffin, John Dillon, Conor McKinley; Simon McCrory, Paddy Burke, David Kearney; James McNaughton, Eoghan Campbell; Conor McCann, Neil McManus, Nigel Elliott; Eddie McCloskey, Conor Johnston, Ciaran Clarke.

Meath v Kerry, Pairc Tailteann, 3pm
The Kingdom will expect to get back to winning ways against Meath, who have yet to earn a point.
They bounced back from an opening-day defeat to Carlow in beating Laois but succumbed to the group leaders last time out.
Meath will take heart from the counties' meeting in the Leinster SHC qualifier group last year, which they won by 3-20 to 2-17.

Meath: TBC
Laois v Carlow, O'Moore Park, 3pm
Laois were fancied to set the pace after surviving in Divison 1B but things haven't gone to plan for Eamonn Kelly's men.
They lost to Westmeath for the first time in 50 years on the opening day and went down by nine points to Kerry second time out.
Laois got back on track with a hard-fought win in Antrim a fortnight ago but must do it again against a Carlow team who have themselves beaten Kerry and retain promotion ambitions.
Defeat for Laois would likely leave them needing a big win over Meath on the last day to avoid a relegation play-off.
Teams
Laois: Enda Rowland; Joe Phelan, Leigh Bergin, Colm Stapleton; Podge Lawlor, Matthew Whelan, Ryan Mullaney; James Ryan, Patrick Purcell; Ben Conroy, Neil Foyle, Ciaran Comerford; Willie Dunphy, Ross King, Stephen Maher.
