Dylan Swetman scored 12 for the Cougars and put HF-L up three with four minutes to go.
That's when Check took over. His layup tied the game at 37. HF-L answered and Check came back with another layup to tie again.
With just over three minutes left, Check hit a step-back three to put the Knights ahead by three. The Cougars pulled within one, but Check drove the left side and swished a 7-foot floater to give Sutherland a 44-41 lead.
One Cougar free throw made it 44-42 with under a minute remaining. Check finished the game off by finding a cutting Alex Bucella, pushing the Knights advantage to four. Two more free throws made it a six-point game before HF-L hit two meaningless buckets to close the scoring.
Bucella scored 13 and pulled down eight rebounds for the Knights (11-4).
