The Browns promoted tight end Connor Hamlett from their practice squad to active roster and waived backup safety Don Jones on Tuesday.
Hamlett was elevated because tight ends Randall Telfer (right high-ankle sprain) and Seth DeValve (left knee) are injured.
Telfer said he's expected to be out four to six weeks after suffering his injury Sunday in a 31-20 loss to Washington. DeValve suffered his injury in practice this past Thursday. He used a single crutch last week but walked through the locker room Monday without it.
Telfer is the primary backup to Pro Bowl tight end Gary Barnidge.
