Both teams will come into the matchup with several names on the injury report, with Cleveland already ruling out two of their players, and the Celtics having four of their key players listed as questionable as of Saturday evening.

The Celtics take on the first-place Cavaliers in a marquee showdown, but they could be shorthanded for Sunday's game.

The Cleveland Cavaliers and Boston Celtics might not be at full strength for their meeting on Sunday. The Cavs will be without Dean Wade who is missing his sixth straight game with a left ankle sprain.

According to MassLive's Brian Robb, Horford's showing against the Cavaliers should be enough proof that he can continue playing beyond the current season. However, Horford will hit unrestricted free agency next summer, meaning the Celtics must move to sign him to an extension, assuming he's willing to push off retirement and continue playing.

The Celtics were a far better team with their 38-year-old center on the floor, challenging shots, grabbing key rebounds, and knocking down 3-pointers in the 120-117 win.
