Olympiacos Piraeus announced on Friday that shooting guard Aaron Harrison will miss three to four weeks with a knee injury. Harrison, a Turkish Airlines EuroLeague rookie, was injured after spending less than 4 minutes on the floor in the team's 66-75 road win on Thursday at Zenit St Petersburg. Until then he had been averaging 8.3 points in 21.6 minutes per game. In Round 4, Harrison hit a game-winning three-point shot on the buzzer to give Olympiacos an 85-82 home win over Maccabi Playtika Tel Aviv. Harrison came to the Reds this summer after two seasons with Galatasaray Istanbul in which he averaged 14.9 points over 25 games in the 7DAYS EuroCup.
