Adam Peaty returned to the Olympic pool for the first time since winning 100m breaststroke silver to help Great Britain qualify for Sunday’s men’s 4x100m medley relay final.
The British quartet of Peaty, Oliver Morgan, Joe Litchfield and Matt Richards registered three minutes 32.13 seconds to qualify fifth-fastest in Paris.
They finished second in their heat, behind the United States who finished in 3:31.62.
France, with home hero Leon Marchand swimming the second leg, were the fastest qualifiers in 3:31.36.
Peaty tested positive for Covid-19 a day after winning silver and did not take part in the mixed 4x100m medley relay heats on Friday.
The 29-year-old could be brought in for the mixed relay final, however, when it gets under way at 20:58 BST.
