Coach John Harbaugh said Wednesday that Tracy is dealing with an illness, Jordan Raanan of ESPN.com reports.
Three days removed from logging just two offensive snaps in the Giants' season-opening win against the Cowboys, Tracy wasn't able to take part in Wednesday's unofficial practice. Harbaugh believes Tracy will be back on the practice field Thursday, after which the team will post its first Week 2 injury report ahead of Monday's game at the Rams.
