Los Angeles Lakers point guard Quinn Cook has been training hard in Atlanta alongside former NBA player Jarrett Jack, according to . report.

Cook said he went three weeks without shooting the rim but has started work. He has also kept in touch with his teammates and coaches of the Lakers.

The 27-year-old has a $ 3 million contract with the Lakers for next season, and is expected to keep his substitute role.

Cook is a triple specialist who has seen little action this season mainly due to the good performance of Alex Caruso, who has split the minutes with veteran Rajon Rondo.
