Monaghan's odds for FL Division 1 honours has been slashed following yesterday's win over Kerry.
The Farney County, who currently lie in second place in the table, are now 6/1 from 14/1 to win the title for a second time having last lifted the silverware in 1985.
Malachy O'Rourke's side now face Dublin in round 7 at Clones on Sunday with Dublin currently 15/8 to retain their crown.
Table toppers Cork are now 9/4 from 11/4 to win the Irish National Insurance Cup for a ninth time.
Meath caused an upset against Down on Saturday night which has seen the Royals shorten into 3/1 from 12/1 for Division 2 success.
Despite remaining top of Division 2, Down have been eased out to 7/4 from 11/10 with Cavan now 9/2 from 14/1.
In Division 3, Fermanagh and Armagh are locked together on 11 points with Fermanagh holding the upper hand on aggregate.
The Ernesiders are 5/2 to win Division 3 with Armagh now 2/7 from 1/3.
Following their win over Offaly, Longford are now guaranteed Division 3 football next year.
The Midlanders now lie top of Division 4 with eleven points and are now 8/11 from Evens to win Division 4 outright.
Liam Glynn, PR Executive at BoyleSports, said: "Dublin remain on course to retain the National Football League but Sunday's match against Monaghan in Clones won't be a walk in the park following Monaghan's defeat of Kerry in Tralee on Sunday."
"Our traders are reporting plenty of interest in Cork at their current price of 9/4. The Rebel County had been as big as 13/2 prior to the League commencing back in January and now holding a two point lead at the top of Division 1, Cork may well put a strong challenge up to Dublin to win the Division 1 this year."
