bleeding player + injury question

[bcl1127]

What would you do if you placed the ball after a play and noticed there was a drop or two of blood on the ball. Then you identify the player with small cut bleeding on his elbow. Then you send the player to the sideline to get it covered up and the coach looks at it and says "he's fine, go back in". After telling the coach to cover the cut, he takes a time out, and is talking about how they have nothing but tape, and he does not was to cover the cut, he still claims in fine, with athletic tape? All the while the coach is telling you that there is no reason the cut needs to be covered up. When you tell the coach there was blood on the ball when I placed it RFP he said, well I'll just tape up you hands then to.

how would you guys handle this? I had the situation this weekend, and then in the 4th quarter, his best player (same one as with the cut) is laying on the ground not getting up holding his knee, so I call an officials timeout and call for the coach. The team in question it up by 28pts. During the time the coach comes onto the field, the player stands up (half way) and limps practically falling over towards the coach. The coach tells me he's fine and I should not have called him out, and I tell him he needs to go off for one play. The coach then proceeds to tell me that I need to learn what I am doing better because the player (who cannot stand straight or take a step without almost falling over) is fine. I make him leave for a play as I tell the coach I am looking out for the safety of the players on the field.

Would you guys have thrown a flag at the coach after incident #2? I just let is pass...
