New York Jets safety Jamal Adams tried to jokingly play into the Jets-Patriots rivalry at Pro Bowl practices this week. And in doing so, he may have sent someone to the hospital.

Adams tweeted a video of him tackling the Patriots mascot, Pat Patriot, on Wednesday. When he was asked about the tackle the following day, he told reporters that the NFL wasn’t pleased with him. The league apparently told Adams that the person in the mascot costume was hospitalized. The NFL itself hasn’t confirmed that detail.

Even if Adams wasn’t trying to hurt the mascot, it’s pretty easy to see how an injury could have occurred. The 211-pound safety hit the mascot just as he turned. Pat Patriot didn’t see it coming at all.

On Thursday, he tried to explain what happened, calling it a “joke.” He said in a separate interview that he didn’t regret the tackle.
