Boston Celtics forward Marcus Morris is still upset at how Thursday's game against the Milwaukee Bucks ended.

The Celtics lost to the Bucks by a final score of 98-97 after star point guard Kyrie Irving missed the potential game-winning shot at the buzzer. Morris was cutting to the basket on the final play and thought he was being held:

Not a day goes by when NBA players don't complain about the refs. However, Marcus Morris may have a point here. It did look like he was being held by Bucks small forward Khris Middleton before Marcus Smart inbounded the ball to Irving:

It was later revealed that the play was called for Morris. 

With the win, the Bucks won the season series against the Celtics. Milwaukee has the best record in the NBA at 44-14. Boston, meanwhile, is 37-22, good for fifth place in the Eastern Conference standings.

Marcus Morris finished with 11 points, six rebounds and two assists against the Bucks in 31 minutes of action. It just seems like the Celtics can't get into a groove right now. The one positive is the next game is against the lowly Chicago Bulls, a game which Boston should easily win.

The second half of the season is going to be important for the Celtics as they try to secure a top-four seed in the playoffs.
