Ennis could only manage seventh in the shot put
Britain's world heptathlon champion Jessica Ennis pulled out of the second and final day of the UK Indoor Trials and Championships in Sheffield.
Ennis, 25, required ankle treatment following her win in the high jump on Saturday and did not want to risk her fitness ahead of the European Indoors.
Meanwhile, former heptathlete Kelly Sotherton won her debut 400m.
Sotherton raced to a time of 53.46 seconds ahead of Kelly Massey and Laura Wake, while Jenny Meadows was fifth.
Ennis was due to compete in the long jump and the 60m hurdles as she builds up to the European Indoor Championships in Paris between 4 and 6 March.
She said: "I have had an annoying niggle on the side of my left foot over the past week.
"I was really happy with my high jump yesterday, it was comfortable and gave me a good insight into how things are shaping up with the European Indoors just a few weeks away."
Sotherton, who made the switch from heptathlon to 400m in 2010, won her first national title.
I feel quite emotional because a year ago I was told my career could be over
"I feel quite emotional because a year ago I was told my career could be over," reflected the 34-year-old following her triumph.
"When I prolapsed the disc in my back it was career-threatening and I had to make a decision whether to end my career or try something new."
However, Sotherton's time of 53.46 seconds was outside of the qualifying time for next month's Europeans. So the Birchfield Harrier will now line up at the Indoor Grand Prix in Birmingham on 19 February to improve her time.
World 800m bronze medallist Meadows said she was disappointed with her fifth place finish. "I don't know what happened really. I'm devastated, I definitely came here to win it."
Meadows will focus on the 800m for the European Championships.
Andy Turner was back on the track after his triumph in the 60m hurdles on Saturday and came second to Danny Talbot in the 200m with a time of 20.94 seconds while Andrew Baddeley took the UK 3,000m title in a time of 7:54:60.
