LAKE FOREST, Ill. -- Chicago Bears chairman George McCaskey traveled back to New Orleans on Tuesday to present tight end Zach Miller with the official game ball from Sunday's 20-12 loss to the Saints.

Miller remains hospitalized after undergoing emergency vascular surgery to repair a damaged artery in his left leg. The tight end appeared to catch a pass for a touchdown on the play in which he suffered a dislocated knee.

A team spokesman said general manager Ryan Pace also is scheduled to return to New Orleans to visit Miller on Wednesday.

Miller had made an over-the-shoulder catch on a throw from rookie quarterback Mitchell Trubisky in the end zone during the third quarter, but when he landed, his left leg bent awkwardly. Officials later ruled that Miller did not maintain possession of the ball.

The Bears announced on Monday that vascular surgeons at University Medical Center New Orleans stabilized Miller's injury, which was diagnosed as a torn popliteal artery.

Bears coach John Fox told reporters on Tuesday that Miller is “progressing well,” but no timetable exists for when Miller might be discharged from the hospital.

Miller has been joined in the hospital by his wife and father since shortly after the injury occurred.

The initial fear on Sunday was that Miller's left leg might have to be amputated, but Fox said Miller's medical team "felt good about where [Miller] was at" in terms of avoiding amputation.

However, Fox doesn't know whether Miller suffered any nerve damage in the leg.

"Not being a doctor, but the feedback I've gotten is the initial concern was the artery and I didn't hear much other than that, so from a prognosis standpoint ..." Fox said. "I don't want to delve too deep into specifics, but that was a big concern and they addressed it, and like I said, he's progressing well."
