Although Grossman is expected to be on the field at the start of mini-camp in mid May, the Bears need an insurance policy at quarterback.
Quinn has been released and George will not be retained. Krenzel will likely go to training camp, but is a long shot to make the 53-man roster.
Whoever signs on will given a chance to move up the depth chart, but will have to prove himself to be better than Grossman and possibly even Hutchinson. Considering the Bears are not the only team looking for veteran help at quarterback, it could be a tough sell.
The Arizona Cardinals are interested in Warner, who he met with Thursday, and appear the easier route to obtain a starting job with head coach Dennis Green not happy with Josh McCown. Johnson has ties to Green from their days in Minnesota.
The Giants have an eye on Fiedler, who would replace Warner as the backup to Eli Manning.
There is a chance the search could expand depending on if Kelly Holcomb remains on the market. He was expected to re-sign with the Cleveland Browns before the start of free agency, but the two sides have been unable to workout a deal.
