During the brief breaks in action in the Wizards’ first summer league minicamp practice — times when Coach Randy Wittman would pause to offer instruction or mild admonishment for a broken play — Bradley Beal would sneak onto the floor to dribble between his legs or toss up a floater before scurrying off to observe. Beal cracked a joke at times or shouted a few words of encouragement from the sidelines, but he clearly would have rather been competing and playing on Monday with the newcomers, Otto Porter Jr. and Glen Rice Jr., and even holdovers Jan Vesely and Chris Singleton. More than three months after he was diagnosed with a stress injury in his right fibula, Beal remains limited and was unable to receive full medical clearance in time to play in the summer league in Las Vegas. Admitting that he has probably hit the frustrating period of restraint as he rehabilitates from injury, Beal also acknowledged that he has to remain patient. “It’s definitely tough, not being able to work out for 12 weeks or whatever it was, and now I’m actually starting to get into it. Gradually I’ll work my way back into it, and hopefully I’ll be back in no time,” Beal said. “It’s definitely going to be a slow progression, and it’s still a little pain on the touch, but as far as hurting when I’m running, it doesn’t hurt at all and jumping at all. But I’m still going to take my time because it might come back on me.”
