Shane Larkin suffers concussion, out indefinitely

Anthony Gruppuso-USA TODAY Sports

It doesn't get any better.  On Tuesday, the Nets issued a medical update on Shane Larkin, who suffered a concussion on Tuesday during practice.  He is out indefinitely.

Here's the update...

Brooklyn Nets guard Shane Larkin has been diagnosed with a concussion, which he sustained at practice on Tuesday, December 15.  He will not return to action until he is cleared to play under the NBA’s concussion protocol guidelines.

Towards the end of practice Tuesday, Shane was knocked to the floor during play.  At the time, Shane only complained of upper back and neck stiffness.  Tuesday night, he alerted team medical personnel that he was beginning to develop symptoms consistent with those of a concussion and was subsequently sent for an evaluation Wednesday morning.  While CT scans for head and neck injuries were negative, Shane was diagnosed with a concussion.  Once he is symptom free, he will enter into the NBA’s return-to-play concussion protocol.  Since recovery time varies in each individual case, there is no timetable for his return.

Larkin has played in all 24 games for the Nets this season, with averages of 7.2 points and 3.6 assists in 18.9 minutes per game.

This is the second time in two weeks that a Nets player has suffered a key injury in practice. Rondae Hollis-Jefferson is out for another two months with a fractured ankle suffered in practice.

Under the NBA's concussion protocol, there is no set timetable for return.  Here are the basic aspects on the "return to participation."

The return to participation protocol involves several steps of increasing exertion -- from a stationary bike, to jogging, to agility work, to non-contact team drills.

With each step, a player must be symptom free to move to the next step. If a player is not symptom free after a step, he stops until he is symptom free and begins again at the previous step of the protocol (i.e., the last step he passed without any symptoms).

While the final return-to participation decision is to be made by the player’s team physician, the team physician must discuss the return-to-participation process and decision with Dr. Jeffrey Kutcher, the Director of the NBA’s Concussion Program, prior to the player being cleared for full participation in NBA Basketball.

It's important to note that there is no timeframe to complete the protocol. Each injury and player is different and recovery time can vary in each case.

The Nets training staff will consult with the NBA medical staff throughout the process.
