SAN DIEGO -- Arizona Cardinals coach Bruce Arians said his overnight hospital stay was due to diverticulitis, an existing condition that flared up before practice Tuesday.The 63-year-old said in a 3-minute press conference late Wednesday morning that hes feeling much better and that he plans on attending Arizonas practice with the San Diego Chargers later in the afternoon.Im too old not to listen to doctors anymore, Arians said. I have a tendency to push it but Ill go out today and see how long well stay. Its nothing serious.Arians has been on a fairly strict diet recently, which made Tuesdays health scare a surprise to the coach.It was odd that it happened, Arians said.Arians said doctors told him to change his diet slightly, drink a lot of fluids and stay inside.Arians said the pain was building throughout Tuesday, eventually causing him to double over about 30 minutes before the joint practice at Qualcomm Stadium was to begin. He was rushed to a local hospital in an ambulance. Arians initially thought he was suffering from kidney stones but didnt show any of the symptoms, which included sweating, a fever or the chills. Arians said he was diagnosed with diverticula during his last colonoscopy.Good thing I do those every two years, Arians said.According to the Mayo Clinics website, diverticulitis is the active form of diverticula, which are small, bulging pouches that can form in the lining of your digestive system. They are found most often in the lower part of the large intestine (colon). When the pouches are either inflamed or infected, the condition becomes known as diverticulitis, of which one major symptom is abdominal pain, the website said. Mild cases are treated with antibiotics, rest and a change in diet.Arians said he knew following the colonoscopy that the condition could flare up.He was mad that he missed Tuesdays practice because it was a good one. Despite quarterback Carson Palmer and cornerback Patrick Peterson joking Wednesday that Arians likely watched tape of the practice in the hospital, he said he watched it Wednesday morning at the hotel.Arians sense of humor wasnt hampered by his health.He joked that his absence from Tuesdays practice was part of his plan to use the San Diego trip as a lesson in being prepared for a changing schedule.Yeah, I did it on purpose, Arians quipped.

RIO DE JANEIRO -- His focus seemingly unflappable, Shakur Stevenson was briefly distracted when he heard a familiar voice as he walked out for his Olympic bout.Augie! Augie!Floyd Mayweather Jr. was in the house and shouting at U.S. boxing assistant coach Augie Sanchez.Stevenson had been bummed out when he was told Mayweather had left the Rio de Janeiro Games. Turned out, the rumor was false and one of Stevensons biggest fans had the best seat in the arena to watch the top U.S. prospect continue his medal run.I got a little more nervous again, Stevenson said.Stevenson, who is from Newark, New Jersey, calmed his nerves and made a lasting impression on Mayweather with a convincing win over Mongolian fighter Tsendbaatar Erdenebat. The retired, undefeated Mayweather went wild for the 19-year-old Stevenson in a unanimous decision victory that guaranteed him a medal.And why not? Mayweather saw Stevenson fight with a style in the ring that reminded him of another great fighter.I see the next Floyd Mayweather, Mayweather said. If anybody can break my records, this young kid right here can do it. I truly believe in him.Mayweather believed in Stevenson (24-0 in international competition) so much that he expected more than gold for Stevenson -- Money May wanted the prized prospect on his blossoming Mayweather Promotions roster. Of course, hell have to compete with other promoters to grab the best U.S. amateur.When I saw him at my gym, I said, `Who is this guy? I want to sign him instantly, Mayweather said. I thought he was a professional. They said he was an amateur but hes got a professional style. Hes the No. 1 guy, of course, that Im interested in.All eyes were on Mayweather more than any fighter in the ring.Mayweather is still the undisputed top attraction at the boxing tournament in what was at least his third visit to the venue. The U.S. bronze medalist at the 1996 Atlanta Games smiled when he was shown and introduced on the big screen to a roaring ovation. Dozens of fans hurried his way for selfies. He never removed the earbuds attached to his mobile phone when he posed for a few fans.They were quickly shooed away and blocked off by members of Mayweathers friends known as TMT: The Money Teamm.ddddddddddddMayweather invited Popo Freitas, a former Brazilian boxing world champion, down to his seat for a quick chat.Mayweather enjoyed the fights, first from the front row of the corner of the bleacher seats, then he moved to dead center for the two American bouts.The 39-year-old Mayweather retired last year after a 49-0 career. The International Boxing Association (AIBA) changed its rules this year to allow professionals to fight at the Olympics, but Mayweather had no interest.He also ruled out a comeback.Im an old man, he said, laughing. Im treating my body good, being smart. I was still able to compete at the top level for 20 years. Ive done a lot in boxing. I just want to give back to young champions right here.Stevenson (wearing a Team Shakur shirt) and some friends and family joined Mayweather in the stands and posed for even more pictures.But Mayweathers A-list pull might not be enough to convince Stevenson to join the team. Stevenson is widely expected to sign a professional contract in the fall with Top Rank Boxing.Stevensons grandfather, Wali Moses, began teaching him how to box when he was 5, and he has barely lost since he won his first fight at 8. Stevensons mother, Malikah, named him after Tupac Shakur, the rapper and social activist who died nine months before her first son was born. Stevenson mostly avoided trouble on Newarks tough streets, and his grandfathers steady influence kept him devoted to his sport.Stevenson remains the brightest candidate to win the first mens gold medal in 12 years from once-proud USA Boxing.Andre Ward was the last American man to claim the top prize with at the 2004 Athens Games, and the London mens team failed to win any medals.Kansas fighter Nico Hernandez snapped the medal drought last week with a bronze.Stevenson has Russian fighter Vladimir Nikitin up next and the winner goes for gold.He was all smiles Tuesday when he had Mayweather by his side as they fought through a mob to escape the arena. Its even better for Mayweather to have his back.Its everything, Stevenson said. Thats the greatest of all time. ' ' '
