Haden sprained his left knee on Oct. 2 against Tennessee. He remained indoors doing rehab and getting treatment on Thursday as the Browns worked out.
Mack, who is still recovering from an appendectomy on Oct. 3, was on the field but didn’t participate in practice for the third time this week.
Coach Pat Shurmur said both players are progressing. Shurmur added there’s a chance Haden and Mack could play against the Raiders even if they don’t practice this week. Browns defensive coordinator Dick Jauron said “it would be a big blow” if Haden, Cleveland’s top defensive back, can’t play.
