Just as the Wizards seemed to hit their stride and get back Markieff Morris from a foot injury that kept him out a game, they won't have Kelly Oubre for Sunday's contest with the L.A. Clippers because he's in concussion protocol.

Oubre, a 6-7 forward who has been a valuable defender coming off the bench or when coach Scott Brooks uses small-ball lineups, is listed out by the team.

The Wizards have won four of five games and might not have Jason Smith (right hamstring) after he removed himself from Friday's win over the Detroit Pistons.

This likely means the Wizards (11-14) will have to play with a tighter rotation or use Andrew Nicholson and possibly rookie Sheldon McClellan, who was recalled from the D-League. 

McClellan was scheduled to return to the team for the weekend before Oubre's injury. Backup center Ian Mahinmi (right knee) is out and rookie forward Daniel House (right wrist fracture) remains out, too.

Oubre's concussion apparently happened in Friday's game. By league mandate, a player who is diagnosed with a concussion "should be regularly monitored for 24 hours for the evolution of symptoms, and accordingly the player may not begin the return-to-participation exertion protocol until 24 hours after the time of injury."

Oubre has to complete a battery of tests, remain sympton free and then be cleared by a physician. There's no timetable.
