Heyward (illness) was listed as a DNP on the Steelers' injury report Friday, Chris Halicke of DKPittsburghSports.com reports.
Heyward missed his first practice of Week 12 after popping up with an illness Friday. While the severity of this ailment is still unknown, the rookie tight end will have two full days to overcome this issue before Monday's game against the Colts. Heyward's status on Saturday's final injury report should shed more light on his availability against Indianapolis.
