The Boston Celtics will be battling against the Miami Heat and their tough defense without two of their key contributors on Wednesday night, as shooting guard Jaylen Brown and forward Marcus Morris Sr. have been listed out with lower back pain and left knee soreness, respectively.

Brown and Morris have averaged a combined 27.0 points, 10.4 rebounds and 1.5 steals per game this season.

The Celtics are struggling to gain momentum late in the season, having gone just 5-5 in their last 10 games and hitting a four-game skid along the way. Boston faced the Heat on Monday as well, escaping with a five-point win as Heat guard Goran Dragic tallied 30 points and five assists to outmatch Kyrie Irving’s 25 points and Al Horford’s triple-double.

Brown didn’t play against the Heat on Monday while Morris would record eight points, three rebounds, two assists and one steal on 3-11 shooting from the field and 2-5 shooting from three-point range.

The Celtics will miss Morris’ defense and presence on the boards against Miami’s bevy of big men as well as Brown’s energy, defense and ability to get into the lane.
