Former Jacksonville tight end Marcedes Lewis is expected to arrive for a visit with the Packers this week.  The six-foot-six, 267-pound veteran could be the blocker Green Bay is looking for, according to one N-F-L source.  He’s not a prolific pass-catcher, but the team doesn’t need that kind of production from the 34-year-old.  The Jaguars released him last March, even though he had a solid 2017 season with 24 receptions for 318 yards and five touchdowns.
