Milwaukee Bucks superstar Giannis Antetokounmpo posted a cryptic tweet, which is being speculated as a reaction to free-agency updates that are starting to come out.

Antetokounmpo posted an eye emoji on Tuesday night. While the post could be interpreted in many ways, fans speculated that it was his reaction to an update on Al Horford's free agency. Before posting the cryptic tweet, the superstar forward liked the post of Adrian Wojnarowski of ESPN.

The Bucks will be an attractive free-agency destination this offseason after showing a lot of potential last season. Milwaukee finished with the best regular-season and looked poised to make the 2019 NBA Finals. However, the Bucks blew a 2-0 lead and lost to eventual champions Toronto Raptors in the Eastern Conference Finals.

Horford will become among the possible targets for contending teams. The 33-year-old center will be a free agent after opting out of the final year of his contract. It was widely expected that the move was made just to negotiate a longer deal with the Celtics, but it appears a return to Boston is not set in stone.

According to Steve Bulpett of the Boston Herald, Horford is no longer discussing a three-year deal with the Celtics and is expected to sign a four-year contract with another team. Losing Horford would be a big blow for the Celtics, who are also expected to miss out on Kyrie Irving this summer.
