Isaiah Thomas puts Celtics fans on high alert with emoji tweet

Boston Celtics All-Star point guard Isaiah Thomas worked his team's trade-craving fan base into a lather Monday night after tweeting an eyes-wide-open emoji.

The last time Thomas sent the same tweet in July, the Celtics signed free-agent Al Horford soon after.

The Celtics sit second in the Eastern Conference, three games behind Cleveland. Armed with a treasure trove of assets, including what might be the No. 1 pick in the 2017 draft via a pick swap with cellar-dwelling Brooklyn, the Celtics have the ammunition that could help them add impact talent before Thursday's trade deadline.

Thomas' tweet left fans and reporters alike scrambling to see if a trade was coming. Celtics assistant general manager Mike Zarren poked fun at the situation when he tweeted, "Life in 2017: A player randomly tweets [eyeball emoji] and [approximately] 20 reporters instantly [text] or call you demanding to know when the trade is happening."

In the aftermath of Thomas' tweet, "Melo to Boston" trended on Twitter as internet detectives scoured social media for hints about possible Celtics moves.

Just when it seemed safe to stand down, Celtics forward Jae Crowder sent out a three-emoji tweet of various playful reactions, including one smiley face with sunglasses and another sticking its tongue out.

The NBA's trade deadline is 3 p.m. ET Thursday. Celtics fans are likely to give their phone batteries a workout checking social media between now and then.
