Parham signed with the Broncos' practice squad Wednesday, Zac Stevens of TheDNVR.com reports.
Parham spent the first four seasons of his NFL career with the Chargers, during which he accumulated 67 catches for 764 yards and 11 touchdowns across 47 regular-season games. The Broncos have Adam Trautman and Greg Dulcich as their top two tight ends on the depth chart, and Parham should have a good chance of being elevated to the active roster at some point during the regular season.
