Question: In which year was this player born who announced his retirement due to a back injury early in the season during the unfortunate 2002–03 Toronto Raptors season?

<P0-S0> The 2002–03 NBA season was the Raptors' 8th season in the National Basketball Association. <P0-S1>  During the offseason, the Raptors acquired Lamond Murray from the Cleveland Cavaliers, but missed the entire season with a foot injury. <P0-S2>  Things looked bleak for the Raptors early in the season as Hakeem Olajuwon announced his retirement due to a back injury. <P0-S3>  The Raptors played around .500 with a 4–4 start to the season, but then lost six straight afterwards. <P0-S4>  The team then suffered a 12-game losing streak between December and January. <P0-S5>  In addition, Vince Carter continued to feel the lingering effect of his knee injury as he missed most of the first half of the season. <P0-S6>  Despite playing only 43 games, he was still voted to play in his fourth straight All-Star Game. <P0-S7>  However, Carter ended up giving the starting position to a retiring Michael Jordan. <P0-S8>  Despite this, the Raptors lost their final eight games of the season finishing seventh in the Central Division with a dismal 24–58 record. <P0-S9>  Following the season, Lenny Wilkens was let go as head coach of the Raptors, and was replaced with Kevin O'Neill. <SEP> <P1-S0> Hakeem Abdul Olajuwon ( ; ] ; born January 21, 1963), formerly known as Akeem Olajuwon, is a Nigerian-American former professional basketball player. <P1-S1>  From 1984 to 2002, he played the center position in the National Basketball Association (NBA) for the Houston Rockets and the Toronto Raptors. <P1-S2>  He led the Rockets to back-to-back NBA championships in 1994 and 1995. <P1-S3>  In 2008, he was inducted into the Basketball Hall of Fame, and in 2016, he was inducted into the FIBA Hall of Fame. <P1-S4>  Listed at 7 ft 0 in (2.13 m) (but standing closer to 6 ft 10 in (2.08 m) by his own admission), Olajuwon is considered one of the greatest centers ever to play the game. <P1-S5>  He was nicknamed "The Dream" during his basketball career after he dunked so effortlessly that his college coach said it "looked like a dream." <SEP> <P2-S0> The Toronto Raptors 2006–07 season is the twelfth National Basketball Association (NBA) season for the Toronto Raptors basketball franchise. <P2-S1>  Following a poor 2005–06 season, General Manager Bryan Colangelo greatly revamped the team roster during the pre-season but continued to build the team around All-Star Chris Bosh. <P2-S2>  Despite a sluggish start, the 2006–07 season transformed into a year for Toronto. <P2-S3>  The Raptors captured their first division title, finished third in the Eastern Conference, made the playoffs for the first time in five years, equalled their best ever regular season record, and secured home court advantage for the first time in franchise history. <P2-S4>  However, the Raptors met the New Jersey Nets in the first round of the playoffs and were defeated four games to two. <P2-S5>  At the end of the regular season, head coach Sam Mitchell and Colangelo were named NBA Coach of the Year and NBA Executive of the Year respectively. <SEP> <P3-S0> The 2014 Rafael Nadal tennis season officially began on 30 December 2013 with the start of the 2014 Qatar ExxonMobil Open. <P3-S1>  This season saw Nadal suffer from injuries that included a back injury, a wrist injury, and appendicitis. <P3-S2>  After losing in the final of the Australian Open where he suffered from a back injury, Nadal failed to defend his titles at Indian Wells, Barcelona, and Rome. <P3-S3>  He rebounded by claiming his 9th French Open. <P3-S4>  Prior to the North American hardcourt season, Nadal would experience another injury, this time a wrist injury which forced him to withdraw from the Rogers Cup, the Western & Southern Open and the US Open where he was the defending champion. <P3-S5>  Nadal announced on 24 October that he would not be competing for rest of the season due to appendicitis and eventually underwent surgery. <P3-S6>  Despite an injury plagued season, Nadal still ended the year at No. 3 with 4 titles.
