The 
National Lacrosse League is the professional league of men's 
indoor lacrosse in 
North America. Indoor lacrosse is a less violent version of 
box lacrosse. Crosschecking and sticks with solid shafts are not allowed; these differences allow more running than in box lacrosse.
The NLL was formed in 1997 from the Major Indoor Lacrosse League (MILL), with the decision to move from league ownership of all teams to individual team ownership. 
Unlike other lacrosse leagues, which play in the summer, the NLL plays its games in the winter.
The league is divided into three divisions:
 Eastern Division 
 Central Division 
 Northern Division
