The Nationals consider Bryce Harper “day to day” after his scary collision Monday night with the right field wall at Dodgers Stadium, General Manager Mike Rizzo said. Harper underwent X-rays on his left leg and left shoulder late last night, and both tests came back negative.

Along with 11 stitches in his chin, caused by crashing into the chain-link fence in front of the electronic scoreboard in the wall, Harper suffered only bruises on his left shoulder and left knee. Tests Monday night determined he had not suffered a concussion, both the Nationals and Harper’s agent Scott Boras said.

Harper “will be sore but fine,” Rizzo said in a text message. “Day to day.”

Harper has yet to address his condition. Tuesday morning on Twitter, Harper responded to the spreading notion that his all-out style may endanger him:

 

In evaluating Harper for a concussion, the Nationals needed to follow protocols MLB established in 2011 to treat players involved in a risky incident, “such as being hit in the head a by a pitched, batted or thrown ball or by a bat; being in a collision with a player, umpire or fixed object; or any time when the head or neck of a player or an umpire is forcibly rotated.”
