It's another blow for Dermot McCabe's side ahead of league opener.
Westmeath have been hit with the news that Ronan O'Toole will be unavailable for selection for this year's intercounty action.
The St Loman's forward has been a key part of the Lake County's attack for the last number of seasons.
His decision comes off the back of retirements of John Heslin, James Dolan, and Kevin Maguire.
Westmeath get their National Football League campaign underway against Louth in Division 2 on Sunday at 2pm.
