Four games into the 2009–10 season, Daniel suffered the first major injury of his career, breaking his foot in a game against the Montreal Canadiens. He suffered the injury after being hit by a slapshot from teammate Alexander Edler. Although Daniel finished the game and recorded three assists, x-rays several days later revealed a fracture. He was sidelined for 18 games, returning to the ice on 22 November against the Chicago Blackhawks. Soon after his return, he notched his third career NHL hat-trick in a 4–2 win against the Atlanta Thrashers on 10 December. Four days later, he was named the NHL's Second Star of the Week with seven points over the course of the week. In the final game of the regular season, on 10 April 2010, against the Calgary Flames, Daniel scored his fourth career NHL hat-trick in a 7–3 win. All three goals were assisted by his brother, helping Henrik pass Alexander Ovechkin for the Art Ross Trophy as the NHL's leading point-scorer. The last goal was chosen by TSN in a fan-voted poll as the NHL's play of the year; Daniel received a between-the-legs tip pass from Henrik near the corner boards before beating goaltender Miikka Kiprusoff with a between-the-legs deke. Daniel finished the season with a career-high 56 assists and 85 points despite playing an injury-shortened 63-game campaign. His 1.35 points per game rate was third in the League behind Henrik and Ovechkin. In the subsequent 2010 playoffs, Daniel recorded ten points in the opening round against the Los Angeles Kings, including the series-winning goal in the late stages of Game 6. Against Chicago the following round, his production decreased to four points as the Canucks were eliminated in six games. In the off-season, Daniel was named to the NHL Second All-Star Team. It marked the first time since 1973–74 that two brothers were named post-season NHL All-Stars, as Henrik had been named to the First Team. They were also chosen to appear together on the cover of EA Sports' European version of the "NHL 11" video game.
