Even Jets coach Eric Mangini appears to be tired of trying to figure out who his starting quarterback is going to be.

A day after Chad Pennington called on the Jets brass to make a decision regarding the situation, Mangini surprised his team by canceling both sessions of yesterday’s scheduled practice, giving it the day off.

The Jets will resume practice today with a pair of practices at 8:45 a.m. and 5:45 p.m. at their training facility at Hofstra. Both practices will be open to the public, so fans can get a glimpse of how Pennington and Kellen Clemens are performing as they vie for the starting spot, while also waiting to see what happens on the Brett Favre front.
