Boston Celtics forward Jayson Tatum suffered an ankle sprain in the closing seconds of Tuesday's overtime win over Turkey at the FIBA World Cup. At first, the severity of his injury was not clear, and some feared the worst. However, according to a report from ESPN's Brian Windhorst, Tatum is already feeling better.

Tatum suffered his ankle sprain with just three seconds remaining in the overtime frame. Trailing by one point, he led his team down the floor on a fast-break opportunity. Once he penetrated the paint, Tatum dished the ball off to Khris Middleton for a game-winning layup attempt. Unfortunately, though, Tatum rolled his ankle in the process.

Tatum was in obvious pain and was later helped off the floor. For this reason, there was serious concern that his injury could be serious. According to Windhorst, though, the Celtics star was able to walk without a limp while wearing a shoe after the game.

Tatum, who is expected to undergo further evaluations on Wednesday, logged just over six minutes in Tuesday's win over Turkey, racking up 11 points on 3-of-11 shooting from the field (0-for-3 from beyond the arc), 11 rebounds, three assists, two blocks and two steals. Middleton led the team with 15 points, followed by Kemba Walker (14 points, seven assists and six rebounds).

For a variety of reasons, several notable NBA players chose to withdraw from this year's FIBA tournament. Team USA will likely err on the side of caution with regards to Tatum's injury, which would leave the American side even thinner than it already is.

Team USA will be back in action on Thursday, as they're scheduled for a matchup against Japan at 8:30 a.m. ET.
