Boston Celtics wing Jaylen Brown hasn't played since March 8 against the Minnesota Timberwolves, when he took one of the scariest falls imaginable in an NBA game -- slipping off the rim after a big dunk in transition and landing hard on his neck and upper back.

Brown, who remained on the floor for several minutes before walking off under his own power, was later diagnosed with a concussion and no further damage. He was entered into the NBA's concussion protocol -- a multi-step process that requires several achievements before a player can return to the court.

On Tuesday, Brown sat on the bench as the Celtics defeated the Oklahoma City Thunder -- a positive sign, since it meant lights and crowd noise didn't bother him. On Thursday, Brown practiced with the team in Portland, and he told reporters he was aiming for a return this weekend against the Sacramento Kings.

Presumably, if Brown has a date in mind, he has passed most (or all) of the concussion protocol and is now simply trying to fully return to game shape. For a banged-up Celtics team still missing Kyrie Irving and Marcus Smart (as well as Gordon Hayward and Daniel Theis, who are both presumed out for the season), getting one of their best defenders and a 14.1 point-per-game scorer back into the lineup would be a big boost.

Still, Brown's mother gave him a specific instruction.

Hard to imagine he will follow that advice.
