Monaghan's Colin Walshe will spend the next six to nine months on the sidelines thanks to a cruciate ligament injury.

The defender sustained the injury early in the first half of the All-Ireland quarter-final defeat to defending champions Dublin on Saturday but did not leave the pitch.

Walshe, in fact, played the remainder of the 2-22 to 0-11 defeat after receiving treatment.

It has now been confirmed the 2013 All Star tore the knee ligament in the incident and he now looks likely to unavailable to Monaghan and his club Doohamlet O'Neills until well into 2015.
