Evan Lysacek‘s return is being pushed back again.
The 2010 Olympic champion, who hasn’t competed since the Vancouver Games, pulled out of this week’s U.S. International Classic in Salt Lake City with a “slight abdominal tear,” according to a U.S. Figure Skating (USFSA) release.
Lysacek, 28, did not skate in 2011-12 due to disagreements with U.S. Figure Skating.
He was set to return at Skate America in 2012 but withdrew with a groin injury. Sports hernia surgery in November caused him to miss the 2013 U.S. Championships in January.
In June, it was announced Lysacek would compete at Skate America in Detroit, which now could be his first competition back. There’s no update yet on Lysacek’s status for that Oct. 18-20 event in light of the abdominal tear.
The brother-sister ice dance team of Alex and Maia Shibutani also pulled out of the U.S. International Classic after Alex tweaked his neck in practice, according to USFSA. The Shibutanis have been the second best U.S. team behind Olympic silver medalists Meryl Davis and Charlie White for much of the last three seasons.
Davis and White will lead the field at the U.S. International Classic, along with 2013 U.S. men’s champion Max Aaron and 2013 U.S. women’s silver medalist Gracie Gold.
U.S. figure skater dedicates long program to Boston
Puma has introduced the “BeatBot,” a self-driving, line-following robot that runners can program to move at a specific pace around a track.
That means one could race against a robot-version of Usain Bolt‘s 100m world record of 9.58 seconds, with BeatBot’s top speed at just over 27 miles per hour.
The BeatBot can also navigate track curves, as shown in the video above.
Puma plans to roll out BeatBot to various track programs around the world over the year.
