News of Roger Federer's knee surgery caught Novak Djokovic by surprise and the world number one said he hoped to see his Swiss rival back on court soon as the sport needs him. Federer said he would miss a number of tournaments, including the French Open in May, after undergoing keyhole surgery in Switzerland last week. Anthony Davis tallied 32 points and 13 rebounds and LeBron James recorded 29 points, nine assists and eight boards, and the Los Angeles Lakers weathered a career-high-tying 41-point effort by Jayson Tatum to beat the Boston Celtics 114-112 on Sunday at Staples Center.
