1	Willis Reed
Willis Reed NBA Photos/Getty Images Date: May 8, 1970 Situation: Game 7, NBA Finals, Lakers vs. Knicks Injury: Severe pull of right thigh muscle. Result: Without Willis Reed in Game 6, the Knicks allowed Wilt Chamberlain to rampage for 45 points and 27 rebounds in an easy Lakers victory. But Reed famously came out of the tunnel for Game 7 and limped onto the the court to a thunderous ovation at Madison Square Garden. The Knicks defeated the Lakers 113-99 to capture their first NBA championship as Reed scored four points on five shots in 27 minutes.
2	Kirk Gibson
Kirk Gibson Ken Levine/Getty Images Date: Oct. 15, 1988 Situation: Game 1, World Series, A's at Dodgers Injury: Strained hamstring, sprained knee ligament. Result: Down 4-3 with two outs in the ninth inning, Kirk Gibson came off the bench to face the game's most fearsome closer -- Dennis Eckersley. Gibson somehow worked the count full despite taking some terrible-looking swings at a few fastballs. Then Eck cut him a break by offering a slider which ended up in the right-field seats for a 5-4 L.A. victory. Gibson didn't bat again the rest of the Series, but he had already struck the biggest blow as the inspired Dodgers went on to win in five games.
3	Jack Youngblood
Date: Dec. 30, 1979 Situation: Divisional playoffs, Rams at Cowboys Injury: Stress fracture, left fibula. Result: In the first half, Jack Youngblood was chop-blocked by two Cowboys, causing his left fibula to snap above the ankle. But Youngblood got the trainers to tape him at halftime and even got a sack of Roger Staubach in the second half of the Rams' 21-19 upset victory. Youngblood used a leg brace the rest of the way as the Rams won the NFC title the next week at Tampa Bay before losing Super Bowl XIV to the Steelers, 31-19. Just for good measure, the future Hall of Famer played in the Pro Bowl as well.
4	Kerri Strug
Kerri Strug Mike Powell/Getty Images Date: July 23, 1996 Situation: Olympic team gymnastics competition, Georgia Dome Injury: Torn ligaments in left ankle. Result: Keri Strug botched her first vault, scoring a measly 9.162 and busting up her ankle on the landing. The pain was significant, but the 4-foot-9, 87-pound gymnast somehow mustered up the courage to run down the ramp and perform one of the most difficult moves in women's gymnastics -- the twisting Yurchenko. The score was a 9.712, enough to hold off the Russians and earn the U.S. its first ever team gymnastics gold medal
5	Byron Leftwich
Byron Leftwich Craig Jones/Getty Images Date: Nov. 2, 2002 Situation: Marshall at Akron. Injury: Broken left tibia. Result: Byron Leftwich went to the hospital for X-rays in the first quarter of a scoreless game. By the time he came back, Marshall trailed 27-10 midway through the third quarter. Leftwich threw for 208 yards the rest of the way but his rally fell short as Akron held on for a 34-20 victory. The outcome of the game, however, long has been forgotten. The enduring image from that night was Leftwich being carried downfield by offensive linemen Steve Sciullo and Steve Perretta after a 41-yard completion to wideout Darius Watts in the fourth quarter and several other big plays.
6	Emmitt Smith
Emmitt Smith Jonathan Daniel/Getty Images Date: Jan. 2, 1994 Situation: Cowboys at Giants Injury: Separated shoulder Result: By the time this one was over, everybody had forgotten that Emmitt Smith had held out for the first two games of the season. Smith broke a long run late in the first half only to have safety Greg Anderson catch up to him and twirl him to the ground awkwardly. Halftime X-rays revealed a separated shoulder, but Smith came back to rush 13 times for 59 yards and catch four passes to lead Dallas to a crucial 16-13 overtime victory that clinched the NFC East title, home-field advantage in the playoffs and a third straight rushing title.
7	Steve Yzerman
Steve Yzerman Dave Standford/Getty Images Date: Spring, 2002 Situation: Stanley Cup playoffs Injury: Blown out knee Result: How badly torn up was Steve Yzerman's right knee? Put it this way: After leading the Wings to a Stanley Cup finals victory against Carolina, Yzerman underwent reconstructive surgery that kept him sideline through the first half of the following season. Playing the second half and the entire postseason basically on one leg, Yzerman was brilliant, scoring 23 points in 23 games.
8	Michael Jordan
Michael Jordan Jonathan Daniel/Getty Images Date: June 11, 1997 Situation: NBA Finals, Game 5, Series tied 2-2, Salt Lake City Injury: Flu Result: Jordan was vomiting all the way up until game time, but you wouldn't have known it by the way His Airness played. Jordan scored 38 points, including 15 in the fourth quarter and a pivotal 3-pointer with 25 seconds left, to cap Chicago's rally from a 16-point first-half deficit. The win gave the Bulls a 3-2 series lead, setting up the clincher a couple of days later in Game 6.
9	Bobby Baun
Date: April 23, 1964 Situation: Stanley Cup finals, Game 6, Maple Leafs at Red Wings Injury: Broken leg Result: A Gordie Howe slap shot forced the Maple Leafs defenseman to be taken off the ice on a stretcher in the middle of the third period with the score 3-3. Bobby Baun had it taped and frozen, came back onto the ice and scored the game-winner in overtime to force a Game 7. Baun, who couldn't walk without crutches, came back in Game 7 as well to help Toronto capture the Cup with a 4-0 victory.
10	Donovan McNabb
Donovan McNabb Doug Pensinger/Getty Images Date: Nov. 19, 2002 Situation: Cardinals at Eagles Injury: Broken right fibula Result: Donovan McNabb isn't just a great quarterback. It turns out he can act, too. After breaking his right ankle on the game's third play, McNabb faked out his coaches and trainers into thinking it was just a sprain. He limited his game to pocket passing, throwing for 255 yards and four touchdowns on 20-of-25 passing as the Eagles crushed the Cardinals 38-14. It was the first time in his career that he did not have a single rushing attempt. Once the X-rays came in though, the Eagles wisely decided to sideline McNabb for the last six games of the regular season.
