On Tuesday, Mike Garafolo of NFL Network reported Sanchez will visit the Bears on Thursday.
Sanchez entered the league as the No. 5 overall pick in 2009 after he thrived at USC, but he never lived up to his draft status. He has played for the New York Jets, Philadelphia Eagles and Dallas Cowboys in his career and sports 86 touchdowns and 86 interceptions overall.
He did lead the Jets to back-to-back AFC Championship Games in the 2009 and 2010 seasons, but that was largely a result of his talented teammates, considering he threw a combined 29 touchdowns and 33 interceptions during those two seasons.
The USC product last saw consistent playing time in 2014 with the Eagles when he threw for 2,418 yards, 14 touchdowns and 11 interceptions in nine contests. He attempted just 18 passes in 2016 for the Cowboys behind Dak Prescott and doesn't appear to be someone primed to turn around a Bears franchise that hasn't been to the playoffs since the 2010 season.
Fortunately for Sanchez and Chicago, he wouldn't have to since Glennon will presumably be the starter.
Sanchez would at least give the Bears a backup with extensive experience at the NFL level compared to Connor Shaw should Glennon disappoint or suffer an injury.
