On Karen Chen's first Olympics and Frank Carroll's last

(This is a combined notebook with my Ice Network colleague Lynn Rutherford.  She wrote about Chen, and I about Carroll.)

Frank Carroll's 12th and final Olympics as a coach ended a day earlier than expected.

Although the premature finish owed to the misfortune of his last Olympic student, Denis Ten of Kazakhstan, it turned out to be advantageous for Carroll, 79, who left for home in Southern California on Saturday, the day after Ten failed to qualify for the free skate.

"I'm sick as a dog," Carroll wrote in a text message Sunday, calling his illness "cold-like but getting worse."

Ten, the 2014 Olympic bronze medalist and two-time world medalist, placed 27th of 30 in Friday's short program. Only the top 24 made Saturday's free skate.

His poor performance was not a surprise, given the foot problems that have plagued Ten since the 2015-16 season and were exacerbated by a severe ankle injury suffered last August. Ten, 24, said Friday it was painful even to put on skating boots.

"It has been incredible," Carroll said of his Olympic coaching career.
