Key starters for the Raptors and Celtics are listed on the injury report for Monday.

Jaylen Brown’s availability for Monday night’s game against the Toronto Raptors is still uncertain. Due to a right knee hyperextension, the 27-year-old forward’s availability to play for the Boston Celtics has been deemed uncertain, the team reported. He is Boston’s only injury going into Toronto.

It will be another shorthanded night for the Raptors without Christian Koloko, Otto Porter Jr., or Jakob Poeltl. It will take at least another week before Poeltl’s sprained left ankle receives further information, and his status has not been updated. During practice on Sunday, the Austrian big man was observed shooting while the training staff examined his ankle.

Gradey Dick, a rookie first-round selection, was on the injury list on Monday morning due to a sprained right thumb. Now that Boston is involved, his status is in doubt. Dick was brought up from the G League to supplement Toronto’s roster in the face of the team’s mounting injury list.

In his twelve minutes of action against the Utah Jazz, he went 0 for 3 from the field. It seems unlikely that he will play much against the Celtics if he is fit, unless the game is a blowout. The 20-year-old was sent to the G League to improve his conditioning after having a terrible debut season.

As Toronto’s starting center, expect Jontay Porter or Thad Young to receive the start. With Poeltl out, Young has been started, but Porter emerged as the stronger of the two and took over versus Utah in the second half. If he gets the start on Monday against the Celtics, that wouldn’t be shocking.
