Al Horford is slightly favored to not be with the Boston Celtics at the start of the 2019-20 season, per BetOnline.ag.

The online betting site has Horford at a +100 to be with the Celtics next season and -140 to be somewhere else. Horford has a player option worth $30,123,014 for next season. If he declines it, the veteran big man would become an unrestricted free agent this summer.

There could be a lot of changes coming for the Celtics this offseason. The team was projected to win the Eastern Conference this season, but they fell short of that goal and were a dysfunctional team all season. The Celtics lost to the Milwaukee Bucks in the second round of the playoffs in five games.

During the regular season, Horford averaged 13.6 points, 6.7 rebounds and 4.2 assists in 68 games. The five-time All-Star shot 53.5 percent from the field, 36.0 percent from beyond the arc and 82.1 percent from the free-throw line. The Celtics were 41-27 when Horford was in the lineup.

Boston is expected to try and trade for New Orleans Pelicans superstar Anthony Davis this summer. Once point guard Kyrie Irving opts out of his 2019-20 player option with the team, the Celtics become eligible to trade for Davis. It will be interesting to see what the future holds for Horford.
