The Green Bay Packers made four roster moves on Tuesday, using the two additions to address growing depth concerns due to injuries at safety. The Packers signed safeties Trey Dean and Tra Fluellen, who were both able to practice with the team on Tuesday, and released offensive lineman Karsen Barnhart and tight end Drew Biber. Biber, a Wisconsin native, was added to the roster during training camp when injuries hit at tight end. At tight end, Biber was the odd man out after the team added McCallan Castles and welcomed international player Thomas Yassmin to the mix over the last week.
