Plaxico Burress isn’t the only free agent visiting the Steelers on Saturday.
According to a league source, former Broncos TE Daniel Graham also will make a free-agent visit.
The Steelers are in the market for a backup to starter Heath Miller after losing Matt Spaeth, who agreed to a contract with the Bears. Graham, 32, is known as an exceptional blocker.
The Broncos released Graham in March after four seasons as the team’s starter. Graham had a $1 million roster bonus due on the first day of the league year and was due $4.2 million in salary in 2011. He originally was a first-round pick of the Patriots in 2002.
