The Boston Celtics host the Oklahoma City Thunder Wednesday night in what has the potential to be an NBA Finals preview. Boston is the defending champion, and OKC has -- far and away -- been the best team in the Western Conference this season.

After Peyton Watson's foul on Jalen Williams, the All-Star slipped on the floor. He took a moment to get up before he held onto his hip area. He only played a few more possessions before being ruled out of the second half with a hip strain in the Oklahoma City Thunder's 140-127 loss to the Denver Nuggets.

The Oklahoma City Thunder are in Boston for a big-time matchup against the NBA's defending champions.While the Boston Celtics are the No. 2 seed in the Eastern Conference, they remain one of the favorites to win the title this season.
