Sen. Kevin Cramer sustained an injury last weekend on his right hand that could require amputation.

The senator revealed in a statement regarding his injury on Wednesday, saying it occurred while he was working in his yard at his home in Bismarck. His initial statement did not explicitly state the extent of his injury. Cramer’s staffer Molly Block later clarified on Twitter that just his fingers were in danger of being amputated, with the senator lamenting that his “future @NFL career is over.”

Cramer explained in an interview with the Forum in Fargo that the injury occurred while he attempted to move an unstable rock on his property. The rock rolled back onto his hand, crushing his ring finger and ripping the tip off of his pinkie. The injury required immediate surgery, and will keep the senator in North Dakota while it is monitored.

“I continue to remain in North Dakota close to medical care as there is a high risk of infection and the possible need for finger amputation. I am alert and in good spirits. Although I am missing this week of votes and hearings, I am monitoring Senate business closely and in constant contact with my colleagues and staff.” Cramer said in his statement.

Cramer plans to return to Washington after July 4, but will likely be absent for the floor vote on the Bipartisan Safer Communities Act, which is set for the end of this week. Cramer had indicated to The Associated Press last week that he would not be supporting the bill.

When Cramer does return to Washington, he says he plans on “doling out a lot of left-handed fist bumps.”
