Celtics point guard Rajon Rondo tweeted this photo with the caption, "LooonnngggO Workout."

Kendrick Perkins and Rajon Rondo will play together again.

Of course, it’s only for one day — Friday at 1 p.m. —  in the Ozen (Beaumont, Texas) High gymnasium where Perkins played prior to joining the Celtics as the No. 27 overall pick in the 2003 NBA draft.

With As the culmination of a three-day basketball camp in his hometown, Perkins will host a celebrity all-star game ^[3], featuring former C’s teammate Rondo, current Thunder teammates Kevin Durant, James Harden and Eric Maynor as well as Bucks guard Stephen Jackson.

With the news that Durant just began negotiations on a potential deal ^[4] to play alongside Deron Williams in Turkey, you can bet news outlets will be making the 90-minute trek from Houston to Beaumont.

Houston native Jackson and Rondo have long been friends of Perkins, also attending the former Celtics center’s 2009 bachelor party and wedding ^[5]. And it appears Perk’s become fast friends with Durant, Harden and Maynor after being traded to Oklahoma City in February and playing just 34 games with his new team.

The news is just one more encouraging sign that Rondo — who tweeted a photo on Tuesday of his healing dislocated left elbow, knees and ankles wrapped after a lengthy workout — is on schedule to be NBA game ready when the lockout ends. Here’s a quick rundown of Rondo’s busy offseason schedule so far …
