The Boston Celtics have all but clinched a playoff spot and are now fighting for seeding. This late in the year every single win counts, in both the regular season and the postseason.

Every roster spot is important, from the starting five to the last man on the bench. On Sunday, the Celtics' G League affiliate is expected to add power forward Thomas Robinson, who is optimistic he can make it to Boston and make an impact.

Thomas Robinson, who turns 28 on Sunday, hasn't seen NBA minutes since the 2016-17 season when he was still with the Los Angeles Lakers. Over his five-year NBA career, he averaged 4.9 points and 4.8 rebounds while shooting 47.0 percent from the field.

The fifth overall pick in the 2012 draft, Robinson has seen time with the Sacramento Kings, Houston Rockets, Portland Trail Blazers, Philadelphia 76ers, Brooklyn Nets and the Lakers.

Boston is currently starting Marcus Morris at power forward, and the 29-year-old has been very productive this season. His main back-up, Robert Williams III, has been serviceable off the bench in his rookie campain.

The Celtics bench, though, is currently a little banged up, with Gordon Hayward, Guerschon Yabusele and R.J. Hunter all listed as day-to-day. If Thomas Robinson plays well in his audition and any of the three need to miss extended time, he could find his way onto the back end of Boston's roster.

At 43-27 entering Saturday, the Celtics hold the fifth seed in the Eastern Conference. However, they are only a game and a half back of the Sixers and the Indiana Pacers, both currently tied for the third seed.
