The Cowboys have said little about the status of tight end Rico Gathers, who remains on injured reserve despite being eligible to return. “Yeah, he’s missed a lot of time,” owner Jerry Jones said after Sunday’s victory over the Chiefs, “and that’s all I can say.” Gathers was diagnosed with a concussion during a training camp practice Aug. 15. The Cowboys kept him on their original 53-player roster Sept. 3 before placing him on injured reserve the following day, giving them the option of bringing him back this season. But, with Gathers still apparently not ready to return to practice, it appears more likely Gathers spends the rest of the season on IR.
