San Francisco 49ers Robinson was selected in the fourth round of the
2006 NFL draft by the
San Francisco 49ers. The 49ers converted him into a
running back. 49ers head coach
Mike Nolan was immediately impressed with Robinson's attitude and toughness during training camp. After a solid preseason, Robinson rose up to the number two running back position behind
Frank Gore on the depth chart. Robinson scored his first and second career touchdowns against the
Philadelphia Eagles and Robinson knocked veteran pro-bowl safety
Brian Dawkins out of the game after running him over before his second touchdown of the game. Then, in week 3, Mike Nolan indicated that he intended to use Robinson more often in goal line situations. Despite Nolan's statement, Robinson's playing time actually would decrease over the course of the season, and he did not score another touchdown. He finished the year with 38 carries for 116 yards, 9 receptions for 47 yards, and 2 touchdowns. On February 28, 2008, the 49ers gave Robinson a three-year contract extension. Midway through the
2008 season, Robinson took over as the 49ers' starting
fullback after teammate
Zak Keasey suffered a season-ending tear in his biceps.
Seattle Seahawks Robinson was released by the 49ers on September 3, 2010, at the end of the 2010 preseason. He was signed on September 6, 2010, by the
Seattle Seahawks at the urging of first-year assistant special teams coach and former 49ers' player,
Jeff Ulbrich, who had been Robinson's teammate for the previous four seasons. On December 12, 2011, against the
St. Louis Rams, Robinson returned his first career special teams touchdown on a blocked punt. On January 19, 2012, Robinson made his first and only career
Pro Bowl as an alternate, starting at fullback for the injured
John Kuhn. On August 30, 2013, Robinson was released by the Seahawks during the final cuts, after the use of a prescription medication shut down his kidney and liver and caused him to lose 30 pounds. On October 22, the Seahawks re-signed him to a one-year deal after his health improved. On February 2, 2014, Robinson caught a pass for seven yards in
Super Bowl XLVIII en route to a 43–8 win over the favored
Denver Broncos. It would be the last game of his career as he retired after the game. ==Post-football career==
