Eastwood's loan with Bradford expired at the end of 2009 and McCall opted not to renew the deal.
But talks between the two clubs are ongoing regarding Glennon with Bradford set to take over Glennon's contract, which runs until the end of the season.
Town boss Lee Clark told the T&A: "At this stage of his career Matt needs to be playing regular football to have a chance of earning a contract for next season."
Glennon has not featured in a senior game since November 2008 after losing the number one spot to Alex Smithies.
But with 369 games under his belt, the former Carlisle stopper would offer the experience that McCall requires.
