People slip in the shower every day. Shampoo drips from one's hair onto the bathtub floor, or soap slickens an already wet standing area. But to break a hand? That's farfetched, if at all believable.

Boston Celtics guard Rajon Rondo suffered a broken bone in his left hand Thursday. He told the franchise it happened in the shower. Rondo has been known to take anywhere from four-to-five showers a day. Skeptics pointed out that Rondo's injury is a closed-fist injury known as a "boxer's fracture." ESPN's Jeff Goodman took it a step further, confirming Rondo's daughter's birthday party was at a trampoline park earlier in the week.

Regardless, the fracture will sideline Rondo between 6-8 weeks. It coincides with the Celtics opening training camp and comes days after co-owner Wyc Grousbeck called the four-time All-Star uncoachable. Add untradeable to that list.

Rondo hasn't appeared in more than 55 games since 2011-12, missing 92 over the last two years because of a knee ligament tear. General manager Danny Ainge has found few suitors for the high-priced, oft-injured point guard.

If Boston is adamant in keeping Rondo, the injury was a blessing in disguise. Rondo's value diminishes with every missed game. He's set to become an unrestricted free agent next summer, along with Jeremy Lin, Ricky Rubio, and Jose Barea. Ainge may not even look to replace Rondo if first-round draft pick Marcus Smart exceeds expectations as Rondo's fill-in.

For all the headaches Rondo causes Boston's front office, he is worth holding on to. He's the only true shooter on an otherwise mundane Celtics club. Rondo averaged 12 points, 11.3 assists, and 1.96 steals per game in three seasons leading up to his torn ACL.

If Rondo can post similar numbers following his most recent injury, the Celtics can overlook his questionable slip-and-fall.
