It has been quite the season for Jimmy Butler, one he’d like to forget. Not so much because of the on-court stuff, but the injuries that have kept him off it. After suffering a bruise to the right side of his ribs in the victory Friday against the Nuggets, Butler was held out of the game against the Heat and was questionable for the road game Tuesday against the Hawks. It was the 14th game Butler has missed, and that’s a number he’s not real proud of. “Definitely,’’ Butler said Sunday when asked if he was frustrated. “I haven’t missed a game, let alone this many games in my career. It’s tough, but I guess it’s part of it. I didn’t know it was part of it like this, but it is. “I’ve never had anything wrong with my foot, my ankle, my ribs, nothing. But I guess there’s a first time for everything.’’
