The loss to the Dolphins has proven more costly for the Cowboys with Tom Dearden (l) now sidelined. Dearden is set to miss Saturday night's home clash with the Broncos and games against Sydney Roosters (home), Gold Coast (away) and Parramatta (away). The eighth-placed Cowboys then have the bye and two home games against Wests Tigers and Canberra to finish the season. "(Dearden) is disappointed but he's also pragmatic about what needs to happen when he's going after his rehab," Payten said.
