Willy's clutch play led the CFL West-leading Bombers (5-1-0) to a 27-26 road win over Hamilton on Thursday. He marched the Blue Bombers 94 yards down the field and found Nic Grigsby in the end zone with no time remaining on the clock to tie the game.
Lirim Hajrullahu then kicked the game-winning convert.
Willy completed 31-of-43 passes for a career-high 361 yards against Hamilton in winning his second offensive player of the week award of the season.
B.C. running back Andrew Harris won his third Canadian player of the week award this year, teammate Ronnie Yell won top defender honours and Hamilton kick and punt returner Quincy McDuffie took the special teams award.
Harris, a native of Winnipeg, recorded 143 yards from scrimmage and scored a key fourth quarter touchdown to help the Lions hand Calgary its first loss of the season on Friday.
Harris was also recently named the CFL's top Canadian for the month of July.
Yell recorded his first career interception off Bo Levi Mitchell and returned it 34-yards for a touchdown midway through the first quarter in the 25-24 Lions win.
McDuffie returned five punts for 105 yards and also returned three kickoffs for 47 yards in Hamilton's loss to Winnipeg.
