Triple M's Hot Breakfast chief footy reporter Tom Browne believes Blues star Patrick Cripps may be suffering from turf toe.

Cripps was ruled out of Carlton's clash against Fremantle on Sunday with a foot injury, but Browne revealed the injury may be more peculiar than first thought.

The turf toe injury infamously sidelined Fremantle star Aaron Sandilands for a majority of the 2012 and 2013 seasons. The injury develops as a sprain of the big toe, caused by hypertension when pushing off the ground to beginning sprinting.

Cripps is highly tipped as a Brownlow contender this season, but is currently expected to miss 1-2 weeks with the injury.

The tough onballer is averaging over 27 touches, 8 clearances and 6 tackles per game while the Blues find themselves last on the ladder.
