Browns Pro Bowler Joe Haden and fellow cornerbacks Buster Skrine and Pierre Desir returned to practice Sunday.
The three players stretched during the 25-minute period of practice open to the media. The Browns are not wearing full pads Sunday.
Haden is coming back from a foot injury that forced him to miss the final two preseason games. Skrine had thumb surgery Aug. 18. Desir missed the final three exhibition games with an injured knee.
Haden and Skrine are expected to be ready to play Sept. 7 in the regular-season opener at Pittsburgh. A fourth-round pick in this year's NFL Draft, Desir might be sidelined for the start of the regular season, coach Mike Pettine said last week.
Defensive end Desmond Bryant, who had surgery on his left wrist Aug. 18, did not practice. He and practice-squad linebacker Keith Pough (ankle) worked out on stationary bikes during the beginning of practice.
