Rumors swirled that Robinson suffered a more severe injury during the Crimson Tide’s Saturday’s practice, but Saban cleared things up on Sunday.Robinson heard the rumors, as well. Robinson said he laughed when the talk centered around him possibly breaking a foot.Robinson was a full participant in Sunday’s open Fan Day practice.“Those were just rumors, so I didn’t feel the need to address them,” Robinson said. “I knew I was fine. Just a little small injury.”Robinson said his left knee got rolled up during a play and that the injury isn’t serious. However, if not for the protective knee brace he wears, Robinson said the training staff told him the injury could have been much more severe.Last season, Robinson dealt with ankle and leg injuries for much of the year, but never missed a start. On Sunday, Saban praised Robinson for his ability to play through injuries.Robinson said it’s all about blocking out the pain.“Something that coach preaches to us a lot is mental toughness, and I think that’s big when you’re working through injuries,” Robinson said. “Our training staff is amazing. It takes mental toughness and a little bit of that magic they work in the training room.“If you want to push through it bad enough, you’ll be able to play through it.”Outside of Robinson, Saban also provided updates on three players with minor injuries:Wide receiver Chris Black has a “twisted ankle” and is day-to-day. Black shouldn’t miss more than another day or two. He was spotted wearing a black, non-contact jersey during Saturday’s practice.“I just got stepped on while running a route,” Black said. “It’s nothing serious. Just a day-to-day thing to see how it feels.”Saban said tight end Ty Flournoy-Smith also has a “twisted ankle.”Saban added that cornerback Marlon Humphrey “pulled a muscle” and will miss a few days.Brown leaves practiceLate in practice on Sunday, sophomore cornerback Tony Brown took a shot from teammate Reuben Foster. Brown was taken to the locker room and did not return. He appeared to be favoring his left arm/shoulder. Brown dealt with shoulder issues last spring.With Brown out, freshman Minkah Fitzpatrick and Anthony Averett both received reps at cornerback with the first defensive group.Henry blocks out clutterAs Derrick Henry enters his junior season, the hype surrounding the Crimson Tide’s running back continues to grow. Henry was featured on the cover of ESPN the Magazine. The latest Heisman odds from Bovado list Henry at 16-1 odds to win the Heisman Trophy. So there’s enough noise around Henry that could cause some to be concerned.“We address that with our entire team,” Saban said of the outside noise. “How do you stay focused on doing the things you need to do to be successful, play your best, be your best and not get affected by external factors, expectations. So you’re worried about what’s happening right now. What can I do right now to affect my performance and not get paralyzed by some of the other things that are happening. We talk to players about that all the time.”As for Henry personally, Saban said he’s never seen Henry as the type to be distracted by anything.“I never really thought that Derrick Henry was the type of guy that was an issue with,” Saban said. “He seems to be able to keep his nose to the grindstone pretty consistently in terms of working to do the things that he needs to do to be a better player.” Lineman Cam Robinson (74) practices during the University of Alabama fan day at Bryant-Denny Stadium in Tuscaloosa, Ala., on Sunday August 9, 2015.TUSCALOOSA — Alabama coach Nick Saban said left tackle Cam Robinson sprained his knee, but should be fine going forward.
