Source: Nate Enderle at workouts

CHICAGO -- Another new face showed up at the Chicago Bears' unofficial offseason workouts.

After conducting all of his post-draft training in Idaho, Bears rookie quarterback and fifth-round draft pick Nate Enderle arrived in Chicago on Sunday, and has begun throwing to his new teammates, according to an NFL source.

ESPNChicago.com reported former CFL standout and new Bears wide receiver Andy Fantuz worked out with the team's offensive skill position players for the first time earlier in the month.

Enderle, who impressed Bears offensive coordinator Mike Martz in a private pre-draft workout, passed for 8,181 yards and 62 touchdowns as a four-year starter for the University of Idaho. The quarterback led the 2009 Idaho squad to a victory over Bowling Green in the Humanitarian Bowl -- the Vandals' first postseason appearance in 11 years.

The Bears were determined to draft a developmental quarterback in 2011 after a 2010 training camp injury to Caleb Hanie ultimately forced the team to cut former sixth-round choice Dan LeFevour prior to the start of the last season.

After the injury to Hanie, the Bears acquired veteran quarterback Todd Collins and waived LeFevour with the intent of bringing him back on the practice squad. But the Cincinnati Bengals swooped in and signed LeFevour to their 53-man roster, leaving the Bears without a young quarterback for Martz to develop in his system.

Enderle is expected to open training camp as the Bears' No. 3 quarterback behind incumbent starter Jay Cutler and Hanie.
