The Timberwolves and Lynx opened the doors of Target Center to the public on Thursday for one of the first times since the NBA postponed its season, but instead of a basketball court and hoops on the floor of the arena, there were chairs and places for people to give blood. In concert with the Red Cross and Anheuser-Busch, the teams held a blood drive for 250 people, Wolves and Lynx COO Ryan Tanke said.
