The Miami Dolphins on Sunday fined safety Don Jones after he sent a negative tweet about Michael Sam, the NFL's first openly gay draftee.

Sam, a 24-year-old All-American defensive end, was picked by the St. Louis Rams in the seventh and final round of this year's draft.

Jones tweeted “OMG” and “Horrible” shortly after the news broke, according to the AP. He has since made his Twitter account private.

“We were disappointed to read Don's tweets,” coach Joe Philbin said in a statement. “They were inappropriate and unacceptable, and we regret the negative impact these comments had on such an important weekend for the NFL. We met with Don about respect, discrimination and judgment. These comments are not consistent with the values and standards of our program.”

Jones apologized for the tweets in a statement.

“I remember last year when I was drafted in the seventh round, and all of the emotion and happiness I felt when I received the call that gave me the opportunity to play for an NFL team, and I wish him all the best in his NFL career,” Jones said. “I am committed to represent the values of the Miami Dolphins organization, and appreciate the opportunity I have been given to do so going forward.”

The Dolphins did not disclose the amount of the fine and said Jones will undergo educational training.
