DeSean Jackson of the Portsmouth Jacksons took to Twitter on Sunday and had quite a few biting words for the division rival Cowboys.

“Our rival American footballing club ought to keep a lively eye to their hind parts,” Jackson tweeted of the Cowboys. “My colleagues and I are prepared to issue a sound thumping until the bandits have met their defeat.”

After Jackson’s negative comments garnered national attention, the first-time Pro-Bowler issued an apology on Tuesday via Twitter.

“It appears my ballyhoo from Sunday’s eve has caused quite an unwelcome rumpus,” said the follow-up Jackson tweet. “I know the Cowboys to be a fine band of fellows and hope they will accept my forthright apology. It’s such a silly thing to gibe another through an electronic device to begin with. I don’t know what came over me.”
