Kent State junior T.J. Lawson's quest to claim a national title in the decathlon at the 2019 NCAA Outdoor Track and Field Championship ended abruptly in the first event of day two on Thursday.

While competing in the 110-meter hurdles at Mike A. Myers Stadium in Austin, Texas, Lawson fell and suffered an injury that forced him to withdraw from the rest of the competition. The former Stow High School star detailed the incident on his Instagram account Thursday afternoon.

"Hamstring tweak over hurdle 1 … Fell over hurdle 2 … Broken collar bone … Surgery Saturday … Back soon … Thankfully it is my non-throwing arm."

Lawson was within striking distance of a national title after placing among the top four in four of five events on Wednesday, including a victory in the shot put. He entered the second day with 4,216 points, and had a shot at his school record of 7,876 points set earlier this year that was ranked fifth in the nation heading into this week.

Lawson captured his third straight Mid-American Conference decathlon title earlier this month. He entered the NCAA Championship healthy for the first time since 2017, when Lawson finished ninth to earn Second Team All-America honors.

"It's very difficult right now, but he's managing," said Flashes Director of Track and Field Bill Lawson, T.J.'s father.
