What were they mainly talking about?

W: Hi, Mike! How are you feeling now?
M: How did you know I was here in the hospital? Is it Tom?
W: I was talking with Bob yesterday and I learnt your right leg had been injured. How did it happen?
M: Their right back Tom knocked me down when I rushed to their goal with the ball.
W: Wow! He must have hit you hard.
M: Of course. He hit me from the back and sent me rolling over here and there. At the time I had a lot of pain. Anyway, they brought me to the hospital.
W: Nothing serious, I hope.
M: The doctor said there weren’t any internal injuries, but I’d better stay here a couple of days.
W: Well, Mike. Take it easy.
M: Thank you for your coming. And thanks for the flowers.
