Bolton have brough a premature end to Lubo Michalik's loan spell with Championship strugglers Leeds.
The 23-year-old was due to spend the rest of the season at Elland Road but rejoined Bolton on Friday after a 24-hour release clause was activated.
The central defender started seven games for Leeds and scored the winner against Plymouth on 7 April.
Michalik signed a three-and-a-half year deal with Bolton in January but has not yet made a Premiership start for them.
