But he is happy he had it in August.
"[It’s] great that we caught it now, obviously it’s great that it happened now than in September," Ball said. "Very unfortunate situation for me, but right now I’m looking up. Feeling great and getting to some running next week. I’m excited."
Ball, who had an appendectomy Monday, was back at the Broncos’ suburban complex Saturday. He won’t be ready to start doing some light running for another week or so, but he attended practice, jersey on, as the Broncos had their first on-field work since Thursday night’s 21-16 victory over the Seattle Seahawks in their preseason opener.
In Ball’s place, Ronnie Hillman has taken most of the snaps with the starting offense. There is a chance, in a small never-say-never sort of way, Ball could participate in the Broncos’ third preseason game -- Aug. 23 against the Houston Texans -- but at the moment Ball is not expected to play in any of the three remaining preseason games.
"Of course I want to play," Ball said. "I want to play against San Francisco in, what, a couple days or whatever. But obviously that’s not going to happen. But like I said, it’s just gradually going along, listening to my body and listening to our great training staff in there. They’re doing a great job bringing me along."
When Broncos head coach John Fox was asked after Saturday’s practice about Ball’s status for preseason games, Fox laid the groundwork for Ball’s next game being Sept. 7 against the Indianapolis Colts in the regular-season opener.
"We’ll just play it by ear," Fox said. "I think we saw plenty of him a year ago, we saw plenty of him in the offseason."
Ball, who has been the team’s top back all through the offseason and into training camp, said Saturday he was awakened with stomach pain on Monday and contacted Broncos head trainer Steve Antonopulos. He had surgery Monday afternoon and Broncos president and CEO Joe Ellis and running backs coach Eric Studesville were among those to visit Ball at the hospital.
Because of Ball’s injury, as well as C.J. Anderson’s concussion in Thursday night’s game, the Broncos have some of their youngest players getting plenty of work in the practice rotation. Juwan Thompson, an undrafted rookie who led the team in rushing with 59 yards on six carries against the Seahawks, even got some snaps with the starting offense in Saturday’s practice.
"It’s an unfortunate situation for me," Ball said. "But the running backs are looking good right now. Looking great. The competition is most definitely there. They’re most definitely making me work for that spot. They’re working for it and doing a great job. I’m excited to see them play."
Ball will be the workhorse in the run game for the Broncos this season. Studesville, Fox and quarterback Peyton Manning have all said the second-year back is ready for the job and big things are expected from Ball in the offense.
The Broncos have not had a running back top 250 carries since Reuben Droughns had 275 carries in 2004.
"I’m listening to the training staff, and obviously we’re going to do some tests to see if I’m capable of coming back, which I’m sure I will be," Ball said. "I’ll be even stronger and ready to go."
